Added support for persistent >= 2.5.
Still compatible with persistent < 2.5.
Compatible with GHC versions from at least 7.8.1 up to 8.0.1.
Added Travis-CI build to confirm GHC compatibility, and catch any possible future breaks.

The type signature changes were adapted from PR https://github.com/prowdsponsor/esqueleto/pull/149, with the addition of CPP for backward compatibility.

For some reason if I use GHC and cabal-install in the .travis.yml file Travis-CI hangs on GHC 7.10.1 and up.

At least using Stackage LTS 1.* gives us the confidence that we can build on GHC 7.8.4 and up.

It's probably a bad idea to mix up travis-ci related changes with this PR.
