Additions and Fixes
Allow ~holding in IF blocks

This is allowed by technically also allowing '- ^~command' or something
like that... even if something is semi-instant, hold is now able to
override that and force the queue to wait regardless. (Real instants
like run instantly, foreach, etc, should still remain instant)
- also, allow taking books with no title meta
