Variable sort-out
bionic removal: handle case when no item for the bionic exists.

Use item_controller instead of itypes map.
Check if item exists before getting it from the controller.
Remove the explicit check to player::bionics because that is done in player::has_bionic anyway.
Check the bionic id, instead of the bionic item id.

Fix some unrelated comparison warnings.
