CVS commit by wheeler: 

Bye bye to another couple of files.  Moved the code around a little bit
and moved what I needed from cached tag into the base tag implementation.

Basically this goes with the idea to not keep around the TagLib::File object
after reading is done, but to create new ones as they're needed since this
is not very often.
