Add hspec testing for servant

[decentral1se]

Hmmmm, I don't think everyone uses Hspec. This change is not generic enough. People who are using Tasty would have to remove this stuff. Thanks though 👍

@lwm I'm a bit vexed, you want to include more content in the repository but you rejected something that would've been almost strictly helpful for people starting out with Servant. Not everyone uses Hspec but most Haskellers I know do use Hspec. There were no tests for this scaffold prior to this PR.

@bitemyapp, righto, merged that there, thanks for reviewing. Closed this one off a little hastily it seems. I see a lot of the other templates have Hspec setup as well. Apologies @algas and thanks for contributing.

@lwm how are you merging these? I usually prefer to use the merge button on the PRs so that attribution is solely to the author and so there's a revert button if someone needs it.

[decentral1se]

@bitemyapp on the command line. The git log shows sole attribution, it's only the Github UI that does the 'with X' stuff. Can big green button from now on if you would prefer.

Thanks @bitemyapp and @lwm
