Respawning KF mod for Residential District

All non-vehicle kill frenzies (i.e. the ones with skull icon) can be
repeated if the player fail it.

All kill frenzies fails are saved, so if you save the game after failing
a KF, quit and load it again, this KF will appear again.

After failing a KF, the wanted level will be cleared, ideal for training.
If you don't want this feature, edit "kf_reset_cops_on_fail" to zero at
line 165 of ste.mis and recompile it using the official compiler miss2.exe.

(do not use mispad compiler)
