dep issue, colons in property values, fix date re

Fixed a dependency issue where there is no npm module patr@>0.2.6.

Values can now have colons in them. Without this functionality, there
is no way to use iso dates.

Fix to iso date string regular expression where milliseconds were not
being picked up.

Added a couple of date parsing tests.
