Expose minimum frame time and update periods for experimentation.

Settings are at bottom of [Startup] in OpenSimDefaults.ini, override in OpenSim.ini to change
Defaults are the same as previously.
More information to come on opensim-dev shortly.
Feel free to tweak but if you do please don't expect any support unless feedback on certain tweaks is explicitly requested.
