Restored "Open In Tab" Checkbox for Bulk Uploads

The "Open In Tab" checkbox had been removed when the Jobs framework was introduced. The checkbox has been restored now so that documents are opened after a successful upload. The state of the flag is stored in the local storage of the browser.

Display number of folder items in library for folders with less than 50 items

When selecting a folder in the library the number of items was only shown if there were more than 49. This restriction has been removed so the number of items is now always shown. For this a new resource bundle key CollectionView_number_of_items_in_selected_folder_singular has been added.
