Closes#1235
This commit introduce a pretty big change on how app data files are
managed. Instead of having multiple `accounts.json`, `settings.json`,
`user.json`, `countervalues.json`, it now store everything in a single
`app.json`. And it does it in an *async* way, so it should prevent some
frame loss.
Migration will be seamless, and will keep `accounts.json` encryption if set.
So no user action is involved.
This changes comes also with some simplification on password handling
(e.g: no more need to store password hash).
/!\ Disclaimer
During development, I ran about a weird issue (~ 3 or 4 times) when my
data was simply "erased" in the file, so back to onboarding, no more settings,
etc. I suspect race/write condition, something with write-file-atomic, but I
didn't managed to reproduce, everytime I tried. Anyway, I feel not 100% confident
with it, so if you guys can test on your side, with your data (with encryption
key or not) it will help a lot!
- Two components: <Track> and <TrackPage>. we should try to ALWAYS use them. only case you might not use them is for imperative events (click, etc..)
- also: introduce a "Use system locale" for the language because analytics need to diffferenciate if lang was set by user of fallbacked. it's also better when we'll introduce new lang to users to directly auto switch to their system's
- started to track some pages and events. there will be more required and we'll have to add some in the next days
