EDTF Formatter Year configuration fix (Issue 2016)

[seth-shaw-unlv]

GitHub Issue: Islandora/documentation#2016

What does this Pull Request do?

Allows persisting the year configuration for the EDTF formatter. Makes the middle-endian special condition case more stringent.

What's new?

• Added default year_format.
• Fixed the copy/pasta the two-digit year option text.
• Added the mysql fix that has been killing builds lately.
• Makes the middle-endian case require day and year as well as the space separator.

How should this be tested?

1. created a record with today's date using the date created field from islandora_defaults:

2. In the default islandora object display mode, the date created display settings inexplicitly says "Do not show year" even though it did:

3. Also notice the two-digit year option copied the option text from month:

4. Select the middle-endian option and select the option to not display the year, save the changes, and view the record noticing that the year still displays:

5. Apply the PR
6. Clear cache
7. Change the year settings to whatever you want and see their formatting correctly applied to your record.

Additional Notes:

I haven't fixed the middle-endian issue yet, but I wanted to get this up in case I'm pulled away before leaving on vacation.
