added snippets for php super global arrays
changed name in the copyright block
changed trigger text for erg tags (based on atoms triggers)
cleaned code
added link_to snippet for erb/rails
removed/reset tab keybinding around inline form use

disabled tab key binding when the inline for was being used to complete
a snippet so that it wouldn’t interfere with tabbing from field to
field, and then put the binding back in place when the inline form was
complete.
