SL-368 - removed enhanced skeleton option from preference dialog. Underlying code is still there but may or may not work with the current skeleton (spine joints?)

SL-375, SL-378 - rudimentary logging info to list joint offsets during mesh import. dae_tool.py work to enable joint offset tweaking.

SL-344 - fixed a problem in avatar_lad with some params in wrong group, added diagnostics to make this easier to detect.

MAINT-6336: Put the timeout upstream of the suspending pump and fire the timeout it. Also some cleanup on LLSD construction in vivox.

MAINT-6338: Add methods for getting and setting boolean properties from gSavedSettings in the HTTPCore. Use those methods to access new key HTTPLogBodyOnError. Dump body of HTTP message to log in case of error if this key is true.

MAINT-6336: Centralize waiting on event pump with a timeout. Shorten the lifespan of a timeout event pump lifespan to be no longer than necessary. Change all references to the LLEventTimer to instead uses the centralized version.

SL-374 - don't allow sliders to modify joint positions if there's already a mesh-imposed override in place.

SL-314 - show bones now colorizes rigged-to joints a different color. Also removed what I think is some redundancy in calculating attachment pos overrides. If it breaks I'll change it back.
