Upgraded to Font Awesome 4.0:

Added new icons:
circle-arrow-right-alt
circle-arrow-left-alt
stack-exchange
expand-left
dot-circle
wheelchair
vimeo
try, turkish-lira (alias)
rub, ruble (alias), rouble (alias) - these icons are now using the unicode "f158" which was previously used by the now removed icon "renminbi"

Icons "renminbi" and "cny" are now aliases for "yen", as the icon that was previously used for those codes has been removed. see https://github.com/FortAwesome/Font-Awesome/issues/1338
added the alias "circle-arrow-down-alt" to "download" icon - this is because of the new circle-arrow-right-alt & circle-arrow-left-alt
added the alias "circle-arrow-up-alt" to "upload" icon - see previous explanation
"stackexchange" was assigned to the "stack-overflow" icon, so I changed the name to "stack-overflow" and made the name "stackexchange" to be an alias for the new "stack-exchange" icon
Updated lib.editor to reflect changes.
