ATM, DRE support. Fan, wheel tweaks.

ATM and DRE support as per usual.

Nerfed fan top speed a bit, adjusted Isp in both fan and rcs, took RCS power down quite a bit (now 1/20th of fan in each direction, at 0.5 per thruster x 4 thrusters), and upped base visual rot speed of fans. Ideally RPM-based spin would be off, and they would operate purely on base rpm with blur discs, but this is plenty fine.

Will needs KAS-ability do people can adjust crafts already launched.

Cleaned up wheel steering and torque curves. Standing-start torque is down to 400, but climbs rapidly to 450 and doesn't drop below 435 until 5m/s, should help move at decent speed up inclines. Can't do anything about the massive over-dampening of the suspension, you need TweakableWheels for that.
