- Added `libconfig` (configuration file library: http://www.hyperrealm.com/libconfig/):
- 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). git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@15572 54d463be-8e91-2dee-dedb-b68131a5f0ec
