Update to walk.js v 1.1

Revised code structure (see /libraries for new files), walk animation
completely overhauled (now using geometric wave generators, Fourier
synthesis and Butterworth LP filtering for selected motion curve
construction), redesigned sidestepping animations, tweaked flying
animations, decreased maximum walk speed in Interface to more natural
human value, improved Hydra support, added support for Leap motion,
animation file sizes optimised, cleared out code used to work around now
fixed bugs, lots of minor tweaks and improvements. walk.js is now under
100,000 characters, but I had to use tabs instead of 4 spaces to get it
below the threshold.
Suppress repeated Hash mismatch debug messages
Base implementation for own reverb
Remove debug
Move AudioEnv packet send to own function

	Audio environment packet moved to own function and out of the
if/else
	So it is now sent all the time, now matter if there are other

Winding order fixes.
Use near radius as threshold, since we need to switch to full screen rendering
whenever any point of the near window intersects the light volume.
