Correct my terminology, remove a few tenses from the roadmap.
New copy of CSV with future tense conjugations (for use in tests) and with a fix to mark the past conjugation of måtte as irregular.
Refactor a little for clarity (primarily using a better variable name for conjugations).
Split out some duplicated code into a helper method. Add tests for future tense.
Rescue SubjectExceptions and point the app to a 404.
Refactor some of the messy code in the conjugation method to tidy things up. Move exceptions from the "has_x?" methods to the method calling them - one shouldn't hit an exception just because they check if a verb is allowed...
Remove checks for requires_subject? and takes_subject?. I'm not using them in Norsk, and have no plans to add additional languages yet, so let's keep things simple for now.
Add support for future tense.
