Allow changing familiars with -familiar

[Luingar]

Familiars are cool
Releveling is not cool.
Please allow us to change our familiar (not just the skin, the entire familiar), subject to the usual cooldowns on familiar selection (once per 30 days or level) with the -familier command (Perhaps an option at the bottom "Change Familier Type")

I think this is mechanically impossible.
We do not have any engine-level function that allows us to manipulate and change the chosen familiar for one another.
We'd have to remove all the familiars and control the entire system through scripts, which is possible...
... but it is a huge ordeal, and very low priority.
