[CLM-3596] Added repository format to data on file node click.

https://issues.sonatype.org/browse/CLM-3596
http://bamboo.s/browse/NX-OSSF325-2

In order to send non-gav data to HDS we need the format and the repository ID to fetch the SHA1 hash. This was the only way I could see to scrape that data from the UI.

There are test failures but I believe they are unrelated to these changes.
