   requested. Fixes the build of plugins on x86_64 architecture.

Not sure it's the proper way,though (basically, simply don't override the length)

* fixed erroneus Spanish translation of TTL, thanks to the forum-user "martintxo" for the hint

* modules/gui/wxwindows/video.cpp: fixed problem where sometime the video doesn't start at the right size.

* modules/gui/wxwindows/interface.cpp: work-around for non working wxToolBarToolBase::SetNormalBitmap() in wxGTK.

Closes #2

* AUHAL module. This module is a auhal output renderer for VLC OSX. It uses an auhal unit to do analog audio processing. This will allow us to dump the coreaudio resampler later on and will also do automatic channel reordering etc. The module currently does NOT work. The rendering callback is not functioning. I do not know how to solve the issue. I'm adding it, because it's the way to go, and I want others to be able to take a look at it and fix it.
