Date/Time Accomodations

[Rick-2CA]

I've rolled back PR #36 in the development branch after testing and discussing the changes with the submitter. As a result of the discussion we should consider the following two accommodations:

• Query for the current user's date/time format in their user profile. Depending on performance this may only be enabled when Set-ServiceNowAuth is utilized.
• Enable a configuration setting for customizing the date/time format. In cases where the glide.sys.date format doesn't match any of the assumptions the module may make a configuration would allow a user to force a match that results in a DateTime object instead of the default string.
