* Now reads Prof.txt to get the professions * The templated professions are based on profession `TrueName` * Adds missing starting equipment * Implements gargish starting equipment * Consolidates some of the code * Moves TC stuff to the TC file. * Fixes some starting equipment that was wrong. Note: * Implementing the original T2A professions is possible on the client side, but requires moving the old clilocs to the current clilocs file. In the current file the entries are blank. * Using the original LBR professions (they match AOS but without necromancy/chivalry) is kind of confusing because the profession indexes are ripped out of the UOTD/UOR ones and have non-sequential indexes. This will probably cause confusion and people will get no templated items when they select the wrong profession.
