Visitor Greeter and Notification

This script
- greets a visitor in local chat
- gives a landmark
- and notifies the owner of the visitor
when an avatar steps on the prim it is in.

Any of the functions can be disabled by "commenting the line out" = adding "//" to the beginning of the line.

PS:
Contrary to what the first reviewer writes, this script DOES work and give out landmarks when someone steps on the object containing it like stated above.
