- Updated VS9/10 project files.
   - Updated `configure` & `Makefile`s.
 - New GM, Commands & Permissions system:
   - '''This is a backwards compatibility breaking update''', please read tid:58877
   - Replaced GM levels with Player Groups.
   - Commands permissions & other privileges now depend on group, not GM level.
 - `@help` command improvements: requires "commandname" param and shows more detailed info about commands.
 - Modified GM whisper system to deliver messages basing on permissions, not GM level.
 - Remote trade request is now possible only if player is allowed to use `@trade` command as well.
 - Added a proper permission to use `/changemaptype` command.
 - `clif_displaymessage` is now capable of displaying multiline messages.
 - All `ACMD_FUNC`s are static now, and the only way to invoke them is with `is_atcommand()`; all client commands (starting with `/`) are now translated into corresponding atcommands (with exception of `/kick` used on monster, as there is no atcommand to kill single monster).
 - Removed nonsense "bot check" triggering when player blocked (`/ex`) Server.
 - Merged `@monster`, `@monsterbig` and `@monstersmall`.
 - Improved flow of atcommand execution to avoid revealing info about online players or existing commands to non-privileged players.
 - Merged `atcommand` and `charcommand` script functions (`charcommand` is aliased to `atcommand`).
   - Fixed `atcommand` script function reading unknown memory area (possible access violation).
