GetFreeInventorySlots() and MergeAllStackables() (#1433)

GetFreeInventorySlots is something I need for the vendor pack space check that i'm still working on.....

MergeAllStackables is used for the slumlord as requested by gmriggs. note that i did not actually test this code. It looks good though.
