Added optimal quality values to plant properties, so they can be set per growable type, eg potatoes could grow more easily in worse conditions. (all set to 1 at the moment though)
Fixed some client #ifdef errors.
Add ogg vorbis source
This was included in /src as I was having problems getting the .c files to compile from /lib in vs - it would probably make more sense to keep them in /lib or just ship precompiled binaries
