Tests should be distributed with the package

[mekanix]

Is your feature request related to a problem? Please describe.
As a package maintainer for FreeBSD I'd like to be able to run "make test" in the ormar port and run the tests. I would catch errors before the port is commited to git.

Describe the solution you'd like
The "tests" directory should be part of ormar-0.11.1.tar.gz (source distribution).
