Add lowres_turn to indicate whether we generate angleturns which are 8-bit as opposed to 16-bit. This is used when recording demos without -longtics enabled. Sync this option between clients in a netgame, so that if one player is recording a Vanilla demo, all clients record in lowres. Subversion-branch: /trunk/chocolate-doom Subversion-revision: 378
