Provide a new method, Pinner.CheckIfPinned(), which will check if
any of the arguments are pinned.  Previously IsPinned would need to be
called once for each block.  The new method will speed up the checking
of multiple pinned blocks from O(p*n) to O(p) (where p is the number
of pinned blocks and n is the number of blocks to be check)

Use the new method in "block rm".
