Selective Backlight/Advanced Softlock - Selective actions based on context

Selective backlight allows the user to choose actions that will not
enable the backlight when pressed.

Advanced softlock allows user to choose actions that  will not be
blocked by screenlock on devices without a hold button.

Both only occur in FM and WPS Contexts.

Update:

  timeout conditional to work in case last_filtered_action_tick was never set

 players to still work properly, removed some previous code including
 ignore_event
-Increased ignore timeout to prevent sd card accesses from interrupting action
 code and turning on backlight
-Changed Unknown action to unmapped action in menu, changed handling code
-Removed unneeded logic and variables for handling unfiltered actions
-Reverted unmapped action code to previous functionality
-Added manual entries (thanks JohnB)
-Removed elusive unhandled unicode character from manual, changed formatting slightly

Actions:
Volume,Play,Seek,Skip

Extras:
Disable unmapped actions
Disable selective backlight on external power
Disable touch during softlock on touchscreen devices
Disable softlock notifications (power button still notifies)
Autolock on backlight off

Method:
Adds a function to ignore backlight on next call
 If selected action occurs backlight is forced on,
 Filter_first_keypress stays intact.

Selective softlock allows selected actions through, bypasses the normal
 softlock routine.

ToDo:
DONE
