Merge branch 'master' of https://github.com/onemenny/ui-select

* 'master' of https://github.com/onemenny/ui-select:
  fix bug when filtering
  making sure new tag (tag added on the fly) is removed when already exists in the list of tags
  fix tagging: when using 'tagging' (add tags on the fly) with refreshDelay, the keyup event fires before or after the 'refresh' (attr) method. added a fix to implement the refresh-delay for the keyup event as well
  ignoring public folder
  adding public to gitignore
  adding safety check that the control is still open cause _ensureHighlightVisible is called using a timeout
  added isNewTagDuplication optional user method to check if new tag (when using tagging where each tag is an object) already exists in the list
  tagging: --making sure no empty elements gets in on paste operation --fix dupes search
  fix bug: when using closeOnSelect with tagging - hitting the enter key sets the new tag but keeps the search input value
  fixing bug - when typing a letter that exists in one of the items in the ddl and then deleting it causes the (tag new item) to persists
  fix lost focus (on backspace or adding new tag) when append-to-body is used
  test
  remove opacity change in dist
  disable opacity set to zero cause of flickering when typing in ddl see (angular-ui#1298)
