- fixed rockmergefield ckeditor dialog so it doesn't show the resize gripper
- updated rockTree so that REST errors will be shown vs silently failing. So if there is a REST issue, itempickers and other rockTree controls will now show an error message
- fixed an issue with MergeFieldPicker/MergeFieldController so that the mergeField "id" is pipe delimited instead of comma delimited. It was confusing the itemPicker :)
