Moved light lop state to viewer_states instead of being embedded to allow for subclassing and usibility by other nodes.

The Connect Adjacent Pieces SOP, when in Adjacent Pieces from Points mode and both a point and primitive 'name' attribute exist, will now prefer to use the point name attribute instead of overwriting it with the promoted prim attribute.

Implemented Material Library LOP performance optimization for translating VOP nodes into USD shader primitives. If the LOP has cooked, it can reuse some of the authored USD stage, and translate only select few affected VOPs, without the need to translate any other ones.

Previously, some OSX users might encounter the SSL error in hkey, sesictrl and etc, because their SSL certificates in /etc/ssl/cert.pem were expired. Fixed this issue by using the SSL certifactes in OSX's Keychain, so they no longer need to manually update /etc/ssl/cert.pem files.
