Add constructors for default units

Before the addition of units, the OME-XML schema assumed certain units.
And the OME-XML Java library had methods that took various sorts of
numbers (Double, Integer, PositiveInteger, etc.) using these units
implicitly.

When converting code from the old API to the new one, it is very
convenient to simply change e.g. "new PositiveFloat(foo)" to "new
Length(foo)" but this only works if there is a constructor for each type
of quantity that assumes the unit from earlier schema versions.
