- fix src_dump resource status when multiple uploaders run for one   resource (main source + many sub-sources). src_dump now contains   information about each jobs running to upload the whole source - upload log file now contains sub-source in filename (so splitted in   different files) - restore sanity check before running uploading (making sure no other   uploading process is running).
