Zircon Engine Initial Alpha Release 25 (Wndows binary, Linux may compile) file

Command host_timescale added, set to 0.5 for half-speed or 2.0 for double speed. This is largely a wrapper around an existing DarkPlaces cvar called "slowmo". This command gives a consistent name to the same function in other Quake engines and Valve. Added "tool_show_position 1" and "tool_show_angles 1" to display that information on-screen for map testing to more easily compare in world positions with the map editor in case of making map adjustments.
