Splitting on Paste only supports first token

Bug description:

Splitting on pasted data only supports splitting on the first token.

Link to minimally-working plunker that reproduces the issue:

[literally any working tagging ui-select instance - see select.js ln 826]

UI-Select: 0.16.1

This isn't a bug in that the code is doing something unexpected, so much as it is unexpected that the code would be written this way. An improvement would be to iterate over splitting tokens and split on the first token that exists in the string.

For example,

for (let token of ctrl.taggingTokens.tokens) {
    var separator = KEY.toSeparator(token) || token;
    var items = data.split(separator);
    if (items && items.length > 1) {
        var oldsearch = ctrl.search;
        angular.forEach(items, function (item) {
              var newItem = ctrl.tagging.fct ? ctrl.tagging.fct(item) : item;
              if (newItem) {
                  ctrl.select(newItem, true);
              }
          });
          ctrl.search = oldsearch || EMPTY_SEARCH;
          e.preventDefault();
          e.stopPropagation();
          break; // only split by one token
    }
}

Can you submit a PR for this (with relevant tests)? (Assuming you weren't going to already 😄)

Is the ES6 for (let .. of ..) syntax allowed?
