Admin Menu Tool - Teleport player to Me

because this is indiscriminate.  There are no checks to make sure the
player's vehicle situation or condition is ok for teleporting without
creating problems.
Admin Menu Tool - Teleport to Player

Admin Menu Tool - GCAM + TP fixes

Adding GCAM for testing and fixes for the teleport scripts.

Added global player variables so that ability to use teleport and gcam
can be set by adminlevel.
