* Fixed a deallocation mistake and some buffer overflows in npc_chat.c after doing rtfm@pcre.txt (all caused by incorrect usage of pcre api)
* Removed underscores in npc_chat.c's variable names (easier to read) * Reindented the whole thing (used spaces half of the time ._.) * Moved npc pcre-data deallocation from npc_remove_map to npc_unload git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@11036 54d463be-8e91-2dee-dedb-b68131a5f0ec
