2070: Fix demo recording with broken maps r=heinrich5991 a=Learath2
Apparently there are maps out there with broken headers advertising the wrong map size. This allows demos to be recorded on those.
Example of such a map is `ctf4_old_d668e9fa_2f472051b26b6bffaa4af8990cf882cafd6364e00e1333b77762cb9911e49464.map`

- videorecorder only works for recording demos now
- demoplayer was modified to allow controll over the time that passed
in order to get perfect fps, IVideo controlls how much time passed,
basically every rendercall sets the time to record the next frame
