Changed range of gain; previous range was too small.

Changed physics algorithm to perform integration over several steps if framerate is slow.
Fixed a fundamental issue in the algorithm where timestep wasn't being used to calculate velocity changes.
Had to change around some parameter ranges since the physics are calculated slightly differently now.

Breaking up physics into smaller integration steps.

SH-1387 Class0 video cards default avatar physics to high

Added appropriate featuretable entries.

Changed this to be expected behavior, where top wearable's characteristics are used.

Took out setting, no longer needed.  Was formely restricted to gods.

Force LLTextureCache::purgeAllTextures to get called in addition to normal cache purging.

Accordions are selectively hidden based on gender.

Tripled spring limit for all params.  Very safe change.

Tripled spring limit for all params.  Very safe change.

"high" graphics settings now give 100% updates, versus 90%.
Changed a simple constant that was acting as a threshold for when physics should be updated (the constant was set way too high, meaning that updates were being skipped).

This change looks more complicated than it actually is.  I basically turned max effect into a scaling parameter, versus a clamping parameter.  Piece of cake, just moved some code around and made minor logic changes.

Fixed bug that was messing up time slices for physics.
