small changes to freetds
see: http://www.php.net/manual/de/mssql.setup.php
libogg, libvorbis: update to 1.3.2, 1.3.4
openxcom: add version 1.0.0
Change to xpra version 0.11.6 as 0.12.5 was not working

Version 0.11.6 was the latest version that I was able to get building
and running on NixOS. Unfortunately my previous commit for 0.12.5 was
an error and incomplete.
Application.ini does not refer correctly

The "Application.ini" provided with Thunderbird does not correctly set the path to the icon location. Visa vi it refers to '$out/lib/thunderbird-17.0.11esr', which doesn't exist, but '$out/lib/thunderbird-17.0.11' does. To remedy this problem I added a new variable called 'verName" which adds 'esr' after the variable '$version'. Then change the variables necessary so that the build process sets working references.

Fuuzetsu suggested putting the verName variable inside of mkDerivation. I cannot surmise.

Minor logic fix

music_directory     "${cfg.musicDirectory}"
playlist_directory  "${cfg.dataDir}/playlists"
db_file             "${cfg.dataDir}/tag_cache"
state_file          "${cfg.dataDir}/state"
sticker_file        "${cfg.dataDir}/sticker.sql"

all refer to ${cfg.datadir}, which by default is "/var/lib/mpd/". 

Parsing for instance ${cfg.datadir}/playlists results in:
/var/lib/mpd//playlists - NOT FOUND.
