* Update Portals Documentation
Correct some grammar to be more explicit and clear. Update example CodePen to better match code found in documentation. Update code example styles to match other code examples (ie. 'State and Lifecycle', 'Handling Events').

There was a small comment overlooked when reviewing the documentation. This fixes it to be accurate to the example as well as grammatically correct.

Did find and replace in TextMate.

The tutorial hints that a change can be made that allows you to go back
in time then click in the board to create a new entry, but the change is
already present in the example code.
This fix removes the hint and re-words the explanation of the change the
example code is making.
After realizing this was the second time I've visited this exact page within a year and second guessing myself that the `textInput` ref isn't actually the `<input />` element. I decided to attempt to make this a little more explicit; you are actually accessing the method on the child class and not the `focus` method on the dom input element. Having them named the same caused some confusion.
* Improve displayName documentation
* displayName docs: higher-order component lowercased to stay consistent with the rest of the docs
* Rephrase displayName reference docs
* Add AgentConf 2018
We are having another edition of the AgentConf in 2018, which has again a strong focus on react, and we'll be skiing again 😎 Last year's PR for reference: https://github.com/facebook/react/pull/8196
* Update conferences.md
* Adding Crowdin config file to master repo
* Updated to include additional files while ignoring localized community files stored on github
* Additional files ignored
* Included additional files in root docs directory
FB bundles wrap warning() calls in __DEV__
Split dev-mode transforms into separate parts:
1) umd+cjs+fb: Wrap warning calls with process.env checks
2) umd+cjs: Replace error messages with minified codes
Also updated transforms to use __DEV__ since it transforms to smaller code after stripEnvVariables is run.
Also renamed 'scripts/error-codes/dev-expression-with-codes.js' -> 'scripts/error-codes/replace-invariant-error-codes.js'
* WIP Improve error message thrown in Fiber with multiple copies of React
**what is the change?:**
Adding an 'invariant' with detailed error message for the problem that
occurs when you load two copies of React with the Fiber reconciler.
WIP:
- Is there any other likely cause for this error besides two copies of
React?
- How can we make the message more clear?
Still TODO:
- Write a unit test
- Write a documentation page and create the link to the page, similar
to https://facebook.github.io/react/warnings/refs-must-have-owner.html
It would also be nice to have a page with instructions on how to fix
common cases of accidental double-loading of React, but we can open a
separate issue on that and let the community do it.
**why make this change?:**
This error comes up relatively often and we want to make things clear
when it happens in v16.0+
**test plan:**
WIP
**issue:**
Fixes#9962
* Add improved warning and docs for 'refs must have owner' in Fiber
**what is the change?:**
- Added warning in the place where this error is thrown in Fiber, to
get parity with older versions of React.
- Updated docs to mention new error message as well as old one.
I started to write a new docs page for the new error, and realized the
content was the same as the old one. So then I just updated the existing
error page.
**why make this change?:**
We want to avoid confusion when this error is thrown from React v16.
**test plan:**
- manually inspected docs page
- manually tested in a CRA to trigger the error message
(Flarnie will insert screenshots)
**issue:**
Fixes#9962
Related to #8854
* Add test for the informative warning around multiple react copies
@gaearon debugged the test for this and now it works!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :)
**what is the change?:**
We now test for the warning that the previous commits add in Fiber, and
also test for the old warning in the stack reconciler.
**why make this change?:**
This is an especially important warning, and we want to know that it
will fire correctly.
**test plan:**
`yarn test src/renderers/__tests__/multiple-copies-of-react-test.js`
`REACT_DOM_JEST_USE_FIBER=1 yarn test src/renderers/__tests__/multiple-copies-of-react-test.js`
* Fix up test for 'multiple copies of react'
**what is the change?:**
refactor test for 'multiple copies of React' to be simpler and remove
some copypasta
* run prettier
* Fix conditionals in 'multiple copies of react' test
**what is the change?:**
When moving the 'fiber' and 'non-fiber' conditions from two assertions
into one, we copy pasted the wrong message into the 'fiber' condition.
This wasn't caught because we were using an outdated name for the
'fiber' constant when running the tests locally with fiber enabled.
This fixes the copy-paste error and we now are actually running the
tests with fiber enabled locally.
* Run scripts/fiber/record-tests
