[galaxy-commits] commit/galaxy-central: natefoo: Disk space usage accounting: Users can see how much disk a history is consuming. Disk used is also a column on the history grid. Users can also forcibly purge a dataset from their history. Included is a script (scripts/set_dataset_sizes.py) which will set the value of the new total_size column on the dataset table (includes the contents of the extra_files_path and metadata files).
