Replace progress bars in ad-hoc commands window with spinners
Progress bar "pulse" method indicates that something has been done. For example, when indexing files, it can indicate that one file has been processed, but the number of files to process is unknown. In case of ad-hoc commands, there is only an indication that Gajim is waiting for the network, so spinner is more appropriate here.
