Fixes for genomespace exporter recieving UnvalidatedValue objects.
Improved job logging.
Remove now less useful local runner command-line log statement (still contend it will be valuable for debugging purposes to be able to tweak and rerun the exact script - but point taken :)) . Remove stray statement added in ff4b5fe. Add new logging statement that logs just the base command-line produced by tools for all job runners. Add little note to runners/__init__.py about how to produce an extended command-line logging (with metadata handling, dependencies, and from_work_dir handling).
More reworking of job logging.
Drop now duplicated log message in drmaa, condor, cli, etc.... Have local job runner report which job script it is running - but log it as a job script. For each job runner log the full command-line which includes dependency resolution and not the base version produced directly by the tool and use the old format from the external runners.
Fix for "'HistoryTagsController' object has no attribute 'security_check'".

Trying to access /api/histories/$history_id/tags gives this error:

Execption in get_object check for History 1723db999e478a37: 'HistoryTagsController' object has no attribute 'security_check'
Traceback (most recent call last):
  File "/opt/galaxy/lib/galaxy/web/base/controller.py", line 233, in get_object

    self.security_check( trans, item, check_ownership, check_accessible )
AttributeError: 'HistoryTagsController' object has no attribute 'security_check'

The same happens for workflow tags.
Merge PR394 from stable.
Followup from commentary on PR394, cleaned up incorrect log.exception usage in base controller.
Rework, improve validation of dataset creation requests.
Being more thorough fixes some potential security problems and will allow some performance optimizations I'm planning.
More performant database interaction during collection creation.
Migrate 22 tools from the distribution to the tool shed.
Remove migrated tools from the tool conf files.
Don't show different multi-run option button if only one option.
Pack scripts.
