Add tests for past tense.
Add a stub past tense class. Needs conjugation rules, but will ensure we pass some of the failing tenses (for tense lists, etc.)
Tests were not properly testing conjugation in all cases. They're even messier now, but they do provide better coverage as a result.
Account for multiple conjugations for a single verb when subjectifying.
Add past tense tests.
Merge fix for conjugation method from master.
Add the Unicode gem for use by one of the Norsk tense (specifically, to capitalise letters like ø).
Add columns showing what to expect for the stem and imperative.
Tests for imperative and stem forms.
Implementations for stem and imperative forms.
Update README to note new tenses with support.
First pass at implementing the past tense regular rules.
Correct verb data reading methods to gsub ' / ' to ', ' rather than just subbing it. This should fix some incorrectly failing tests for the past test.
Fix error in qualification of conjugations.
It's only irregular if it's marked with a "*". "/" might just mean there are multiple allowed forms.
Update verb data to mark the many, many past irregularities there seem to be in Norwegian.
Remove a few irregularity markers and cover the conjugations with another new made-up case. Naughty.
Mark velge as irregular in the past tense.
Undo earlier "fix" which added a new class of conjugation for the past tense. It didn't work - there were other irregularities I managed to overlook.

While we're it, remove superfluous empty irregularities hashes from the verbs.json file.
Refactor integration tests to try and tidy things up a little, increase readability.
Add tests for failure when trying to use a subject with non-subject tenses.
