create NetworkStatusIndicator component
add forks/chaintips and lagging property to qenetwork
add synchronizing and synchronizing progress properties to qewallet
Note: new wallet synchronizing is not picked up in UI yet, missing
an is_up_to_date event at the start still..
A user provided an invoice that requires feature bit 30. (That bit is not in the spec)

In commit 9bba65199e,
the QRCodeWidget was put inside a BoxLayout as a workaround to avoid the "copy to clipboard" and
"save as file" functionality grabbing extra whitespace/stretch/padding and putting it into the
exported image.
However, in turn that commit introduced a bug, where making the dialog larger does not make the
QRCodeWidget larger (which worked prior).
This commit tries to fix the regression and also the original bug.
If keystore.check_password is called with some pw on a keystore that does not have a password set,
it now raises better exceptions: it should now always raise InvalidPassword, and with a nicer msg.
Previously the exc type would depend on the ks type.
Examples before change:
```
