Fix NeoTF support

[NukemD]

Foxbot used to better support NeoTF, but somewhere after the last official 0.701 build, it was mostly broken. Foxbot didn't support all NeoTF features to begin with, but it used to support more features than it does now.

Engineers in 0.701 used to occasionally build multiguns, and team bots would actively seek them out to upgrade them, enemy bots would also try to destroy or capture them if they weren't upgraded. Currently 0.8xx, the bots almost entirely ignore them and will be mowed down in perpetuity. The only class that will try to do anything with them is Snipers. Snipers will attack any multigun, regardless if it is enemy or friendly. This is a problem because multiguns are damaged by friendly fire and can't be repaired.

Medics used to both spawn medpods and snarks. Now they only spawn medpods. Medics also used to try and upgrade dispensers to medic dispensers by touching them, now it's just chance whether a medic touches it by accident.

Pyros used to use freeze spray, now they don't at all.

The other classes don't use any of the NeoTF features as far as I'm aware. The Spy will inadvertently use aqualung if it is enabled.
