Searchable texture menu

Simply enough, often I know exactly what texture i want, or from which textureset, but theres missing some kind of easy way to find the texture you want. I think a simple filter (based on texturepath) such as in the svn vars menu would do the trick. If its easy to implement, me (and probably other regular mappers too :p ) would appreciate it.

#757 fixes this.
