Merge branch 'master' of https://github.com/singularity-viewer/SingularityViewer

Conflicts:
	indra/newview/llfloateravatarpicker.cpp - Includes to v-d style, since plain alphabetical just won't cut it. Shyotl's changes for name system, here.
	indra/newview/llpanelgroupinvite.cpp - Shyotl's changes for name system, here.

Also corrected new README to have less typos and be slightly more accurate.
