Earlier today I pushed a change that split this code up into multiple
repos, but that has proved to complicate things too much. So we're
back to a single repo, except the individual submodules are better
separated than they were before.
The README files need updating again; I will push them out soon.
Aside from splitting out the different modules, the sound code has
moved from from anki to aqt.
- tabs became difficult to read when users had a lot of templates, so we
use a combobox instead
- move the More button to the top and integrate adding/removing
templates
- start with no focus to avoid accidental modifications
- display confirmation before adding template
- remove 'edit to customize' text that some users had trouble editing
