- Rewrote/cleaned up trade.c for a more clean trading implementation.

- Added @request commands, sends a request to all connected GMs of lowest_gm_level or above as a whisper message. Defaults to gm level 20 users.
- Made SC_COMBO status start delay attackabletime and walkdelay by sc's duration regardless of skill used (previously it was only for TK kicks, now it's for both those and Monk combos)
