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.

Actions:
Volume,Play,Seek,Skip

Extras:
Disable unmapped actions

Disable softlock notifications (power button still notifies)
Autolock on backlight off

Method:
Adds a function to ignore backlight on next call

 Filter_first_keypress stays intact.

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

is based from.

might need some tweaking, but works.

Add the following actions to %Tp:
createbookmark   create a new bookmark from the wps
listbookmarks    list bookmarks from the wps
trackinfo        show track info from the wps

My main motivation was to allow bookmarking and jumping around audio books
from the wps on touch enabled targets.  You can do it now through the context
menu but it requires 4 screen presses instead of 1.

Just use a bool to indicate raw button instead of action code. No
bother with plugin version yet again so soon.

Change-Id: I4aa075c0c1fb5308c9d49bebb30ac76f671b2335

Adds a new context, CONTEXT_RAWBUTTON, that I hope is out of the way
of everything. Unfortunately have to increment min plugin API version
for the second time today to accomodate additional parameter.

Change the none action return value so the various action layers don't get confused by ACTION_TOUCHSCREEN return codes which shouldn't be happening (i.e when a long press region overlaps a short press region whihc has the none action)

Change-Id: I63db2c0b49597ada2c5ebd0ef98e99aeef4f522a

Modify the %Tl() tag to add a new region 'lock' which will lock/unlock the wps/sbs from touches (hardware buttons still work)
You can also specify a region to work when locked by prepending ^ to the action name (this is probably about to change though)

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)
