Start implementing basic conjugators
Add conjugators for several more major verb families
Declare radicals as variables

This requires a small amount of meta-programming magic.
Replace is_implemented with a custom Conjugator
Declare suffixes instead of writing code
Register conjugators using a decorator
Fill in a bunch of high-frequency irregular verbs
Double consonants in verbs like 'jeter' appropriately
Reorder ay/ai suffixes in imperative for consistency
Conjugate lots more verb forms
Move imperative to an endings-based system

This helps with verbs that conjugate like -er, and hurts with verbs that
have an irregular second-person plural.
Add literary forms for foutre

See notes here: http://www.wordreference.com/conj/FrVerbs.aspx?v=foutre
Handle principal parts of more verbs
Continue working down the list
Handle minor variations on a few existing forms
Implement all regular verbs through 99.9% coverage
