Token control script for roll20

TokenControl

/* Token control script
make a macro called TokenControl, 
the body should read:
!TokenControl @{target|token_id} @{selected|token_id}
To use this, select a token that you want to alter the control of
then click the macro from your bar
then target a token of a player. I think the same token could work.
This will, hopefully, alter who controlls the selected token.
If the targeted token's player had control, it will remove it
if it did not, it will add it. */
