- Add support for using material icons on launcher items (for plugins)
- Allow plugins to omit icons
- Update plugin docs
- add developer note so the next one working on launcher will not spend
hours debugging the wrong place as I just did :)
- Add surface shift option, start from surface by default (previously
was surfaceContainer). Old colors can be attained by changing it back
to "container" in theme colors
- Remove borders on surface elements, mostly
- Fix popup distances
- Use surfaceContainer/sch by default on widgets
