Move all airmap related stuff to its own directory

Added AirMap settings (SettingsGroup)
Added AirMap settings block to General Settings
Create macros to deal with the tedious repetitions within SettingsGroup
Removed old, hacked in setting for AirMapKey
Remove a few of the tons of build warnings

Also hand carried text to speech changes from Stable to master. Plus
unit tests for that.

Too complicated supporting both modes as editor becomes more complex

- You can now cancel parameter change
- Tablete friendly
