Ability to record the demo camera movements

FruitieX created issue #517 (old tracker) on 2011-06-15T13:31:55Z:

Requesting a feature for the democamera so that one could record angles/origins/follow modes into a file and then use this when rendering. It should be possible to make adjustments to these later as well in case you screw up something when recording the camera path. Should be a good project for new coders :)

it’s not hard, only needs to know few QC things for it fopen, fgets, fputs, fclose, R_SetView #is about all one needs for it :P
