Bugfix: Incorrect handling of JSON properties

* Any properties that were not a scalar had an issue when being transformed to and
  from JSON. This is now fixed.
* Truncated values with known units reasonablt so that they are more readable in
  tables. For example, 1.23400000001 kJ/mol is now 1.234 kJ/mol.
