SingularityViewer/indra/plugins/cef/media_plugin_cef.cpp
Lirusaito e62261edb2 Sync with Alchemy, includes much awaited lib updates for Linux 
Applies ALCH-420 - Replace all invisiprims with fully transparent texture and remove dead code paths
-ARC no longer takes invisis into consideration.

Syncs some script keywords updates.

Changes all "\n" in llfloaterabout.cpp to '\n' because screw.dat
