- New Feature: Allow attaching and using underbarrel weapons (by Flugente & JMich)

o You can now attach weapons to other weapons (only one at a time). Comes with additional fire modes (by cycling in tactical with key 'b')
o A new item, the KAC masterkey, demonstrates this. Raider and Kelly have one in their starting kit 4. (pics by smeagol)
o works both in OCTh and NCTH. Aiming is done via the main gun, but all physical values of the attached gun are considered.
o reload an underbarrel gun while it is attached by dropping the ammo on the main gun while an underbarrel fire mode is active. Cycle firemodes in tactical by pressing 'b'
o Attachments to underbarrel weapons are inseparable while weapon is attached, but they do work.

- Overheating weapons additions (by Flugente)
o New option OVERHEATING_DISPLAY_THERMOMETER_RED_OFFSET controls how red the temperature bar is at the beginning.
o New option OVERHEATING_SET_ZERO_UPON_NEW_SECTOR sets temperature of items on the floor to zero if loading a new sector
