Merge lp:~osomon/unity-2d/crash-rtl into lp:unity-2d

[Olivier Tilloy]

[dash] Work around a bug in QML that causes a crash when the layout is mirrored (RTL locales).

Notes to the reviewer:
 - This is merely a workaround to a bug in QML, it will eventually be removed once the actual bug is fixed in Qt.
 - To reproduce the crash, either run the dash with an RTL locale (e.g. with LANGUAGE=he_IL.utf8), or modify libunity-2d-private/src/unity2dapplication.cpp to comment out the code that makes the call to QApplication::setLayoutDirection(Qt::RightToLeft) conditional. Then open the dash, click on "More Apps" and then click any application.
