User defined settings

It would be great if you could have a set of user defined settings under the settings menu option. These could then be mapped to lua variables in the watchmaker editor.
wm_user_settings1, wm_user_settings2 etc.

There would be many advantages with this, e.g:
* Easy to change watchfaces settings for users who are not proficient with the watchmaker editor.
* Can change settings in watchfaces that are not editable (protected)
