Improved support for "Short Date" fields

Browse Source 
* Separate -D (date only) and -T (date/time) format options in mdb-export and mdb-json

* New public mdb_set_shortdate_fmt() function in libmdb

* New private(ish) mdb_col_is_shortdate() function

I'm calling it "shortdate" in order to preserve the existing API.

See https://github.com/mdbtools/mdbtools/issues/12
