Add the free text date

[rlb179]

Add the "free text date" which in the MODS record will be a date without any attributes. The “free text date” is displayed to end users while the keyDate will be used for searching/sorting. For example the free text date in jewels_aal_000 should be
circa 1830
(Note: The free text date in the DLC is ca. 1830 but circa should be spelled out.)

To formulate the free text date follow the instructions in the Omeka Data Dictionary:
"This is the display form of the date. Date may be entered in structured form, e.g., 1935-07-09 or textual form, e.g., July 9th, 1935. Use circa, approximately, or other appropriate term, when the date is uncertain, e.g., circa 1945. Spell out rather than abbreviate the term, thus circa not ca." https://wiki.cul.columbia.edu/display/metadata/Omeka+Data+Dictionary

Per instructions on Jewels in Her Crown MODS Conversion (2014) this element should always be populated.

Will generate from date_single/start date. Date that you refer to ('ca. 1830') was connected to 'publisher date' in original data. So actually, I'll generate first from the publisher date, then where not present, from the single/start date.

Fixed.

Circa already spelled out in all cases - unless I'm missing one. Will review MODS output for this as well. Unless that was added just for further instruction on key date versus human-readable date...?
