[Touch devices] Dropdows work unstable

[Piotr Jasiun]

Tested on CKEditor 4.3.4, Chrome 33 on Android 4.4.2.

When I press style combo to open dropdown:

• sometimes nothing happens,
• sometimes list works fine (usually when I press it for the second time),
• sometimes I lose a selection.

When I check Android device with a hardware keyboard (Asus Eee Pad Transformer, first generation) I found out that everything is fine as long as the hardware keyboard is plugged in , so probably the reason of this bug is the software keyboard.

On the Galaxy Tab 10, this always seems to result in the dismissal of the software keyboard and loss of the selection

Dropdown dismissal was caused by window's resize event that is fired when software keyboard is hiding/showing. Introduced reposition() method in floatpanel plugin. My solution is to reposition the floatpanel on resize event instead of hiding it.

Merged to master with ​git:205e4df. I made only couple of improvements in the manual test. This was kinda brutal solution, but it should do the job and it's logical.

Good job!
