WIP: GT db record for 2017 MC

[tpmccauley]

• Create a record for the 2017 MC GT db
• Additionally create a record for the 2017 collision GT db
• Fix a typo in the 2016 MC GT db record
• Closes #3695

One question to resolve is whether or not to have a separate record for the 2016 and 2017 collision GT db when they point to the same file. The other option would be to make a new record for the GT MC db, modify the GT for collision data to include references to 2017, adding a new link.

The XXXX and YYYY in the json file refer to the as-yet-undefined record ids
