I ran into countless random exceptions and errors locally due to
cache I built up over time that was no longer valid. Though in
approved commits in the repository there is only 1 version as of
now, I'm sure we will make changes in the future that require a
cache invalidation since getHtml needs to be able to make
assumptions about what properties exist.
Also fixed a bug in the parse() method where the 'deprecated'
property is asserted the wrong way around. Added a test for it.

* Add unit tests for all types of invalid input we check for.
* Add unit tests for all types of input we expand or otherwise
normalise.
* Implement InterfaceText expansion/normalisation.
* Fix bug that caused a string value in the root description property
to be considered invalid (it only accepted an object, it should
accept both).
