   404s on no id param and is asynchronous (kkellyy, #133)

   user and re-check for git conflicts if in pickme/added state (kkellyy, #134, #137)

 BUG FIXES

 * copy_dict in core/util now ignores keys not defined in original dict (kkellyy, #130)
 * Pushmaster message users no longer case-sensitive (kkellyy, #130)
 * checklist servlet no longer generates spurious 500s (kkellyy, #132)
 * Explicitly add --no-rebase on git merge conflict testing to guaranteed
   git behvaior (kkellyy, #135)

 * No longer gzip responses by default. (kkellyy, #131)
