[8324] Add WARNING file and drop the EULA

Basically, the reason for the EULA removal is to ensure the validity of
the GNU GPLv2 license, which might be invalidated in some countries by
the EULA.
Instead, a WARNING file with (hopefully) clear statements has been added.

The basic meaning remains the same - every user should check if he/she
is not breaking any local laws by MaNGOS usage.
And the MaNGOS team/project will not provide any resources/help for
(possible) illegal public usage, simply to protect everyone willing to
help, including services through which the help could be provided (ie. forum).
