Was producing out of order settings as a result of the switch to vectors

Without this, the Reset All Settings button would be selected by default

Improve storage requirements.

Unecessary, and would run every time the settings are logged.

Fixes essentially a shadowing issue.

Not sure how I missed this earlier, but these vectors can be constructed
using the type of the enum.

settings_common: Remove unused optional

Reduces some ugliness in frontend code.

Suggests to a frontend how to represent each setting.

This gets rid of some repeated code and sets us up to send more
information to the new widget.

Currently unused, but I don't want to start headaches when someone
decides to use it the first time.

Renames enum values to conform to naming convention.

The new enum macros don't support setting values directly.
For LastAA and LastFilter, this means we need a simpler approach to loop
around the toggle in the frontend...
