This commit adds the new feature to tag reports for specific releases.

It includes a star to highlight a release report and the option to tag
the report with a label for a specific release.

The report will be shown in the `Releases` column of the main page,
under the specified tag name or with name 'untagged' otherwise.

The star/tag behaviour in the report is as follows:

  - Tagging a report will add it to Releases automatically
  - Star checked will add report to Releases (even if no tag is present)
  - Star unchecked removes report from Releases (even if a tag is present)
  - Removing tag but star checked will still keep report in Releases

This commit adds two main components:

  - Migration update to add Starred table
  - CSS star icon
  - JQuery library
