Admin map teleport and safer plyr->ME & ME->plyr

Safety checks and velocity nulls for teleporting.  Map teleporting
rudimentary first try.  I do not suggest map teleporting while moving,
especially flying.
Admin map teleport function small improvements

Restructuring if then else
Forgot macro.h in MAPTP

Added #include <macro.h> to beginning of file to get benefit of __GETC__
construct.
Inserted MAPTP water warning.

MAPTP over water will require RELOGGING because character will become
permanently swimming.
Merge pull request #21 from jwo7777777/master

Catchup branch with mundane master fixes
GCAM improvements

GCAM will now start up behind the selected player from the Admin Menu.
Fonts reset to ArmA3 compatible fonts so font errors will be gone.
Still some issues with UI config items that are missing.  Just click ok,
the warnings will not affect operational stability.
