Frameworks: SlimPIE extended (1/2)

This commit introduces SlimPIE. A very popular feature which
was till now for us no point to integrate it because it did
not fit our concept. Now I found a bit time to program a PIE
which is much more extended then the usual kanged PIE on
most roms but still resource friendly. At this point
many thanks for the great basic idea to PA and the work
from Jens Doll from CM. Based on this ideas SlimPIE goes
it's way now.

@kangers....we would like to see if you can wait till we
released this feature this week.  Thanks a lot.

Features of SlimPIE

- custom Buttons (user can choose between 11 different default actions (like navbar/hardware key bind)
  + custom app/shortcut for every button
- custom longpress action for every button (user has  same possibility like the normal custom Button)
- button quantitiy up to 5 buttons (so 5 + 5 longpress actions are possible)
- selectable trigger positions + trigger width (with optical help to set up)
- turn off text and status information + abillity to hide statusbar information which are redundant
- turn off snap points
- turn off background
- ability to use SlimPIE only on expanded desktop as well as using it always
- integrated logic disable triggers which can conflict with system actions
  (like statusbar or navbar.....SlimPIE detects if one is present and turns this edge off
  temporaly)
- same for snap points
- option to disable bottom trigger and reduce left and right trigger when
  IME keyboard is active

Style feature:

- button color + transparency
- button pressed and button longpress color + transparency
- button outline color
- snap point color
- text color
- background color + transparency
- for every shortcut user can choose a  custom icon from gallery
- custom icon color
- custom icon  color mode (only system icons eg or gallery icons + system icons or all icons)
- Pie size

Also it is possible via overlay to set a minimum, default and max trigger height
due that some phones need a bit adjustment on that (this setting reflects on
the trigger seekbar in settings user can adjust)
