Jonathan Gordon 485ff79584 Add an ability to set a setting to a specific value with a touchscreen action. 
example: %T(0,0,20,12, setting_set, repeat, off)
That will set the repeat mode to "off" when it is pressed.
"setting_set" is the action name
"repeat" is the name of the setting in the config files
"off" is the value to set it to (same values as the legal values in the config files)

Not all settings are supported, outright unsupported settings will fail to parse. Some settings might not work too well if they don't apply instantly (Any that work well int he quickscreen should work well here)
