wxwidgets/*: Readd the labels in the buttons. Should solve the l10n problems on win32. (Revert [14249]) (Refs #646)
po/*: Update the Po to reflect the changes.

* another update of the German translation by Mathias C. Berens | welcome-soft <berens@welcome-soft.de>. Thanks again.

* do only check-out revision 501 of the x264 library, because 502 breaks the linkage of the x264-module on ppc-platforms

* try to fix a crash in case p_input invalidates while waiting for the variables. Found by joneskoo, fix inspired by Meuuh.

Reupdate changelog

* re-activated the Swedish translation in the interfaces

* updated and partially (re-)added the Georgian (by Alexander Didebulidze), Hebrew, Hungarian, Hindi, Russian, and Italian (all by Rosetta translators) localisations
