My actual code before new sandbox was released.

I'm sure in a few days we'll update all code to new server version. So,
I prefer to push my findings for the actual server.

Differences with main version (I won't push, as I know many code is
still uncompleted and my code style differs from Fabian ^^U):

- Addon system: All addons sent by client are checked and answered. Be
careful: DB update is needed (check SQL/Updates/CharacterDB folder) and
a DLL for zLib code is included and needed.
- Fixed wisper code: Credits to Yohaky for pointing the bug
- Implemented distances to yell, say and emote distances: As I saw on
WoWWiki, the distances are different for yell/say/emotes visibility. So,
you only read/see /say texts on the right range, read/see all /yell
texts and read/see all emotes in range
- Emote system: You can see animated and text emotes. Still missing some
emotes (the /dance -which have a proper system- and the ones related to
Stance position of the character -kneel, sit, sleep... Others can't see
you do it yet, but they will read it-)
- Join Channel: Not fully implemented. Only coded the join channel but
still to do the main system (change areas, users in channels...)
- Movement opcodes: I think all movement opcodes are coded, but some of
them still fail on some flag...
- AFK/DND status checked: But not fully implemented. I don't know where
to store it (into DB, in char session... I'm doing some experiments here
:P)
- Chat commands (check /help to see the new ones): Implemented some chat
commands to teleport to AreaPOIs and WorldSafeLocs from DBC files. Also,
AreaTrigger and EmotesText DBC files are parsed and loaded into memory
to be used into some methods.
