Automated multi-hit location attacks

This is a big request, but here goes:

Make it so that when you hit the attack button when using Random hit locations and multiple attacks, it rolls a separate hit location for each attack and uses a unique DR value for each hit location, if defined in the sheet. So basically, GCA assigns the DR for each hit location, and then gCalc uses that to fully automate a long attack process (i.e. bad guy spraying down a PC with an AK-47).
