Merge branch 'release/3.0.0-beta-5' into development
Fixed horribly broken SteerToFollow
Fixed Acceleration/Deceleration rate description

The previous description mistakenly stated that it was in units/second,
which was the original plan but not what I ended up doing.

Reformatted AutonomousVehicle to fit the standard.
Standardized formatting

Sorry for the massive commit of mostly whitespace changes, but I can't
stand having non-standard formatting across all files.  I'd held back on
doing it to minimize the file changes on across minor 2.x releases, but
have got to bite the bullet at some point.
Removed unused #define from Biped, clarified description
Renamed UpdateOrientationVelocity -> SetCalculatedVelocity

The original name didn't really make sense, since it had significance
only in the case of the AutonomousVehicle - for Bipeds, the velocity is
divorced from their orientation.
Unified tool classes under a single namespace
SteerForCharacterEvasion refactor

- No need to subtract the vehicle's velocity when fleeing.
- Replaced an unnecessary ?: use with Mathf.Min
Updating read me and change log for RC1
