S60 softkey refactoring (support for merging, priorities and menus)

Implemented features:

Softkey Merging:
Widget can set only one softkey and set flag that rest of the softkeys
shall be taken from parent.

Priority Handling:
If multiple sokftkeys with same role are set, the highest priority
action gets displayed.

Custom Softkey Menu:
By setting QMenu to QAction and assigning a softkey role for that
action, the native menubar will be displayed when sofkey is clicked.

Softkey Image:
Initial code for implementing sofkey image support, the final
implementation is still pending legal acceptance to use
eiksoftkeyimage.h header file which is under EPL license.

Task-number: QTBUG-7315
