* Renamed the 'PyPAD.Update::dateTime()' method to
	'PyPAD.Update::dateTimeString()'.
	* Changed the format of the 'dateTime' field in the PAD JSON structure
	from RFC822 to ISO 8601.
	* Added a 'startDateTime' field to the 'now' and 'next' objects in
	the PAD JSON structure.
	* Added a PAD Type enumeration for use in 'PyPAD.Update'.
	* Added 'PyPAD.Update::hasPadType()' and 'PyPAD.Update.startDateTime()'
	methods.
	* Removed 'PyPAD.Update::hasNowPad()' and 'PyPAD.Update:hasNextPad()'
	methods.
	* Added support for '%d(<dt>)' and '%D(<dt>)' wildcards in
	'PyPAD.Update::padFields()'.
