Positronic Brains in Mechs Can't Be Removed

[pitaden]

It's currently impossible (as far as I can tell) to remove a brain from a mech without destroying the mech entirely. The brain is unable to eject itself, and people like roboticists aren't able to take the brain out.

suggestion would be to add a tool act proc that will remove the brain after some amount of time. for balance reasons it should take a decent amount of time in the case of rogue silicons.
