Filter Languages in metadata editor

There were already a few complaints about having too much languages in the
dropdown list of metadata audio and subtitle editor. I would say this is
reasonable perception :)

The last one I remember:
http://xbmc.org/forum/showpost.php?p=441428&postcount=2626

I think the suggested resolution in the above post would be fine, if is
possible: 
"please add the ability to type in the desired language for audio and
subtitles in the meta data editor, or make the drop down respond to follow
up keys (like for example if i type in G it goes to first lang with G, if e
is followed in a certain time it jumps to Ge and so on, you get the point -
like an autocompletion feature)"

An other solution could be to only populate those languages into these
dropdown boxes, which are included in Lang/Languages.xml file. Then users
can remove/add languages in that file as they wish. 

Other suggestions are also welcome...
