Update the version of .user.js file(s) passed as arguments

File is edited in-place, and the version is set to YYYY.MM.DD.N format

automatically.

If version is missing, one will be added.

If ran more than once a day, N will be updated.

UTC date is used.

Add or update version in the metablock:

To test without modifying file, use stdin:
