* Removed commented-out code for check_fake_id()
* Merged improved/cleaned up (WiP) code for clif_parse_WisMessage * Removed the requirement to provide a character name in the message string when calling is_atcommand() (needed for the previous fix) - currently both ways work, but old will be removed in the upcoming command cleanup so please adjust your custom code if you use this! * Added clif_process_message(), an unified way to validate all four types of player message packets and retrieve their components * Applied the new checking function to clif code, this fixes various length mismatches caused by incomplete code in r11386 (bugreport:198) git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@11507 54d463be-8e91-2dee-dedb-b68131a5f0ec
