Added the feature of selecting an animation from combo boxes and it playing automatically if it should be at this moment.
Now for the stuff only developers will understand:
FloaterAO is now a FloaterSingleton, because it should've been behaving that way all along.
Refactors a lot, simplifies a lot, best view without space changes.
Reduces a lot of redundant blocks.
Creates some functions to make things like AOStates easier to get
AOStates are now an enum instead of a bunch of const ints.
Cleaned up includes.
NULL -> nullptr, virtual->override, BOOL->bool, for->foreach
Removed struct_tokens, it was redundant and actually just took up space.
No longer set all the children invisible, their parent does a good job of that.
Relate ComboBoxes to their states, so that we can easily get a setting and do a whole bunch of things with a lot less code.
Remove unused parameters and functions and variables
Remove unused boolean returns from functions.
Don't clear combo boxes just because one id is null.
Cleans up some related code, probably looks nicer with space changes off.. though this is a pretty straightforward change.
Comments out code that still exists in xmls or might likely be added in future.
Each piece tested quite a bit.
