Allow to nickname models

[Chase22]

There have been multiple suggestions on renaming models and i think it mainly breaks down to:
Models get confusing.

When i get a decent structural design on a model i tend to stick with it, but that gets confusing very quickly. Is my Abraham IV my mobile lightly armoured anti-infantry tank or my heavy anty-armor laser tank?

I think without much change to the existing numbering system it would be nice to give model iterations a nickname which gets shown together with the model name. So i then have Abraham IV 'Howitzer'

I agree, this would be a great change.

Likewise, I wanted to make a designation between my Howitzer tanks and my high velocity tanks but the naming convention doesnt make this feasible. I also wanted to put the gun caliber in the description but this is also not workable as it spreads across all models.
