Core/Guilds: guild code was completely refactored and rewritten.

* OOP desing and implementation;
* all the queries are moved to prepared statements;
* guild loading is optimized;
* all the possible interaction with guild's data is done inside the guild class;
* added more hooks to GuildScript class;

WARNING: Make sure you backup your characters database before applying this change (just in case).

Known problems with guilds:
* when new member is added to the guild, MOTD is not displayed for him in guild tab of social window;
* if you add item with random property to guild bank visual representation of item below it becomes wrong (it displays wrong stack number);
* packets order differs from official: currently guild bank packet traffic is twice as more than on offy.
