Second version, in more of a playable state

Core:
Fixed include list, added proper credits for ZCMD (thanks Y_Less!) and
added links to all the dependencies.

Match:
Set name tags and map icons to be hidden from the seeker and shown to
the hiders.

Changed the seeker weapon from an MP5 to a desert eagle (eventually this
will be customisable along with many other things via a file, hopefully
someone wanting to run this gamemode won't even need to know Pawn or
compile it and set everything up via files)

Added KickPlayerFromMatch to remove them from the game and put them into
spectate mode.

Player:
Fixed a problem with GetPlayerColour by adding an array of colours
(from: http://wiki.sa-mp.com/wiki/ColorFix)

Added spectate mode and LMB/RMB for clicking through players. Spectate
mode is used for AFK players, players that get "kicked" from the match
and player who join mid-match.

Added an "API" file that will contain callbacks from any match/player
event in the script so developers can easily write addon scripts that
hook these events (such as scoreboards/stat lists, anti-cheat, admin
controls etc).
