Added [in:shadowlands] and [in:torghast] extended conditionals.
Added #nounshift meta-command, which accepts extended secure command options. If its argument evalutes to next, the auto-unshift behavior is disabled for the next slash command in the macro; if it evalutes to any other value, it is disabled for the remainder of the macro; if none of the conditional clauses apply, no change is made.
Fixed an error that ocurred when an action bar containing an M6 macro was being animated out.
