Clamp ODE character velocity. Make ODE falling character 54m/s by default.

Browse Source 
If velocity reaches 256 in any vector then bad things happen with ODE, so we now clamp this value.
In addition, a falling avatar is clamped by default at 54 m/s, which is the same as a falling skydiver.
This also appears to be the value used on the linden lab grid.
This should resolve http://opensimulator.org/mantis/view.php?id=5882
