Hotkey for using items on self

[Xavieri]

A thing that has been bothering me for a while now is that there is no way for spacemen to use items on themselves if they cannot see their own sprite, be it when inside lockers, pods, bushes or other things of that nature.

So, a simple fix would be to add this function to a hotkey. Pressing it would be basically the same as clicking on your sprite with your active hand. No more jumping into the void of space to slap patches in my face.
