Vanilla port

[Rochet2]

DONE:

• Messaging works
• Addon sending works
• Compression works
• Examples work
• Saved variables work
• Had to change server->client message length to 255 to prevent crashes
• sending message to multiple players in one call is now disabled, send the message to each one separately

TODO:

• Saving position does not work yet, LibWindow is disaibled.
• There are debug prints and comments etc that need to be cleaned up
• The code is messy and should be cleaned up
• Client and server files are currently different
• Cores take in different params for the Whisper function. Need to pass in correct param based on core (guid vs player)
• Docs need to be updated to reflect new functions and changes
• Should test how drunkenness etc affects the messaging
• There are a few TODO comments that need to be fixed

Classic quirks:

• Many functions do not exist: select, match, #, print, SetSize
  • equivalent functions can be defined by hand or some alternative needs to be used like SetWidth and SetHeight.
• Functions work differently: find, unpack, SetPoint
  • equivalent functions can be defined by hand
• Event arguments are passed through global variables called: event, this, arg1, arg2, arg3, ....
  • we need to check if we are on vanilla client and use vanilla args instead
• _G is not exposed, math.huge does not exist, global variables are not global and must be set with getglobal and setglobal
  • create functions and definitions for same purposes
• strings do not have methods
  • instead one must explicitly call string.find(s) instead of s:find()
• Addon messages cannot be sent as whisper
  • Instead use normal whisper and hide the messages from chat.
• Long comments using [====[ syntax does not work
• varargs do not work in the same way
  • Some workarounds are to use tables and unpack or use fixed amount of parameters (ARGS_MAX)
• the key n in tables is reserved and should not be used.
