Updated icon library/added to git

Also fixed some color/highlighting CSS rule conflicts.  Library is
saved on icomoon.io as well now.
Type fix
Fixed buttons hover cursor css rule
Fixed home nav not highlighting
Topbar re-org/enhancment

Changed user preferences to icon only vs username as that was a bit
confusing and too long in some cases.  Need to add the username
indication back somewhere else probably later on….
