Alt+Click Doesn't Work Correctly For Silicons

Created by: Shadowmech88

As a vox/diona/human/skeleton, if you alt+click an object, it pulls up the list of everything that's on that tile. As a silicon, it only pulls up the list if you alt+click on the floor. Alt+clicking an object does nothing. This means that if the tile has a 32x32 object, it's impossible to click on the floor, and so impossible to get the list for that tile. In general, it just makes things more difficult on cluttered spaces because you have to pixel hunt.
