British only verb conjugation?

[jstafford]

I'm finding word_forms to be very useful, and I really appreciate you putting it out there.

One small issue I ran into is with the word "model"

Here are the results I get:
{
'n': {'modellings', 'modelings', 'modeller', 'model', 'modelers', 'models', 'modellers', 'modeler', 'modeling', 'modelling'},
'a': {'model'},
'v': {'modelling', 'modelled', 'model', 'models'},
'r': set()
}

As you can see for the noun forms both British and American spellings are provided, but for the verb form, only the British conjugations are shown. I haven't dug into the code yet to see how it works, but if there's an easy fix that would be great.
