QuickAction was adapted to HD-screens.

Hi, i fixs bug in shown QuickAction at larges screens.

QuickAction correctly shown at small screens, her width is width of screen.
And QuickActtion correctly shown at large screen, and her width value is MAX_WIDTH_POPUP_WINDOWS constant. Arrow  shown is correctly, too.

+ Add constant MAX_WIDTH_POPUP_WINDOWS;
* Set min SDK version(API 7, as before) and target SDK version(API 15).
