Limit province names to 15 characters.

See the long names here: https://pastebin.com/S0ZQfD9M

Why? Because it is annoying to type other provinces names in RC. Copy & paste? That's annoying too (on mobile especially).

A name should be unique, short, and distinctive. Like real world names. No one's got the time to spell your full name, or find the "unique" shortest sequence of characters to represent you.

Why does Utopia have to be so verbose? If people want to be creative in their names, there's plenty of room in 15 chars to do it (68% can, the rest are themed mostly). Most twitter handles are shorter than this.
Limit it, and people will still find ways to be creative. Make it large, and (some) people will use it up. A goldfish grows to the size of its bowl.

Flame away.
