Fix for garbage data in vertex weight array crashing software skinning.
Proper integration of picking for rigged attachhments.
Optimization in LLDrawable::updateDistance (don't call updateRelativeXform, just use spatial group position).

previously built package depended on an updated glibc, which our build hosts
don't have (they're old debian systems). This is due to Ubuntu turning on
stack protection by default for its builds (I build on Ubuntu).
This updated package was built with no stack protection and thus should
unstick the build.

updating install.xml to use the new glod autobuilt library.

build machines. Can be re-applied when our build machines get an updated
version of libuuid.
