/*
 Click Overrides

 These are overrides for a living mob's middle and alt clicks.
 If the mob in question has their middleClickOverride var set to one of these datums, when they middle or alt click the onClick proc for the datum their clickOverride var is
 set equal to will be called.
 See click.dm 251 and 196.

 If you have any questions, contact me on the Paradise forums.
