Archive Release

[TimothyBJacobs]

Releases need a way to be archived. Archiving a release reduces the amount of data we have to store.

A release can only be archived if it isn't the latest release. Releases can be automatically archived after a certain amount of time.

When an archived is released, we aggregate all of the data in the itelic_updates table for that release, and delete all of those rows.

• [x] Number of updates for each day for the 14 days after release
• [x] Aggregate data of the 5 most popular previous version
• [x] Percent complete

Implemented except for archiving scheduling which has been moved to #49.
