Functionality not yet in packagist

[recycledbeans]

Hey, thanks for adding the trait for being able to use the uuid as the primary key @danhunsaker and @kilrizzy. I noticed this feature does not seem to be in a tagged version, so it's not installable via composer without using dev-master. Any chance we can bump the version number for packagist?
