disable prim tesselation 'split' factor - almost useless for deferred rendering, easily wastes ~20,000 triangles per frame.

merge the changeset 4de3178c6c81 from viewer-development: fixed the major memory leaking for SH-723/SH-847: memoy leaking

SH-808 making sure the 10m vs. 64m scale limit switch happens for both the spinner and the manipulation tools etc.

Fix the case where the silhouette shown when editing a mesh in an adjacent region
was showing up in the wrong place.  The silhouette was not being translated
by the avs view with respect to the region.

SH-841 Hide physics parameters in build tools when connected to a region that doesn't support additional physics parameters.

Fix for redundant calls to stateSort(LLDrawable*...)
Put back "Build Queue" info display.

Raycast debug view was not translating by the agent origin

Fixed this issue.  Also, viewer-development has a duplicated "Region Debug Console" entry.  I assume this duplication is a mistake / bad merge so I took out the duplicate.
