Change UUID database column type to CHAR

CHAR has some performance advantages over VARCHAR. Also Laravel uses CHAR(36) for it's new uuid type introduced in v5.2.

If you later decide to upgrade the migration schema to Laravel's uuid type, the underlying database schema wouldn't change.

Interesting I didn't know about that char type. You state it was introduced in l5.2, meaning it won't work in 5.1 ?

Looking at the commit, it looks like it's a ->uuid() type, which internally uses char, so I'm assuming that ->char() type was here before.

Yes CHAR has been there since forever. The new uuid just creates a char(36).

Awesome, thanks.
