Picking up token cancels rescue and elusion

As it is now players can cast elusion/rescue before picking up a token
to port to another location and quickly deliver it and other players
have very little chance to get there in time to stop them.

This change cancels elusion and rescue when a token is picked up and it
also makes so potion of deliverance and chalice of the rain does not
work when a token is "equipped"
Spelling errors

Fixed spelling errors, replaced if's with CancelRescue() function
instead and added a message that you cannot cast rescue while holding a
token.
