Added migrations for gdb_pe robot cert and 'background' tag. Also added 'background' to the list of blessed tags in the settings module.

Put my virtual environment earlier in the search order of PYTHON_PATH. For some reason, this became necessary after apt-get dist-upgrade.

Fixed handle_uploaded_data to check whether the likelihood column is inf. Replaces 'inf' with the largest value that can be accepted by the mysql database. Fixes issue 1171. But we might find ourselves needing to check other columns in the future.

The IVORN must have a hash sign between the fixed part (the 'ivo' bit) and the event-specific part (the 'resource number', or in our case, the graceid).

commit. Here, self.version is set on the VersionedFile object.

Fix for Issue #975, 'Versioned files displaying only newest versions in event detail page'. To fix this, we add a file_version field to the event log. This is accessed from the VersionedFile object at the time of file-saving. That way, the correct version can always be associated with any given log message.

I (Branson) found this local change to refresh_users_from_ldap on archie. It looks harmless, so I'm keeping it.

Made changes to bring VOEvent closer in-line with what Mina and Peter are proposing. However, I still don't have their AlertVersion property. Nor do I have any of the analysis specific stuff, like ChripMass, frequency, etc.

Added basic 500 template. I did this because sometimes Django gives uninformative error messages (while in DEBUG mode) if the 500 template is absent.

analyst_comments and data_quality tags are blessed,
 but were not in the fixture for tags.
