The library annotations are a new lint and we have no need to specify a
custom library name anywhere. The JS annoation on the library also did
nothing, since it doesn't default to the library name in dart and only
modifies the prefix of functions if you pass in a custom name.
The sqflite_common_ffi I removed the upper constraint, which allows us
to use a newer version if our dart version is new enough, but I left it
at the original version because there is no need to require a higher
minimum currently.
- migrated to more useful MSC directory structure
- migrate Widgets API into new structure
- add recent emoji API into new structure
The recent emoji API is non-standard and should be compatible with Element.
