* Fixed global chat logging always crashing on a null pointer
* Applied changes to clif_parse_globalmessage() from my WiP code
- clearer processing of the individual packet components
- proper code ordering, some more integrity checks
- fixes to some poorly chosen ShowWarning() format strings
- global chat logging no longer logs the entire string (w/ player name)
