* 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)
