SL-1291 - fixed some issues with selection highlighting of objects rezzed while in build mode. Not clear whether this addresses the original issue, which isn't reproing

SL-9680, SL-9673 - set attachment distance floor at 0.01 to avoid triggering divide-by-zero prevention logic. Force HUD attachments to always be full detail.

SL-966 - animated object size/pos constraints cont, including some settings for debugging. additional options to anim_tool.py for making test animations

SL-966 - size and pos limit calcs moved to sep method. Global scale option for testing of size limits.

SL-944 - logcontrol options to control which log recorders get used. This can be useful for performance reasons when especially verbose debug logging is needed.

SL-937 - added debug setting DebugObjectLODs to help track LOD calculations especially for rigged meshes

SL-937 - use dynamic box for rigged mesh attached to normal avatar as well. Still has a 2x error in the radius calc, but gets radius using the dynamic box.

MAINT-8863 - less verbose diagnostics, kept the fix. Make sure joint nums get rebuilt after invalid joints are scrubbed.

MAINT-7926, MAINT-8400 - fixes related to bounding box and LOD calculations for rigged meshes in animated objects
