Various Housekeeping Tasks

[creichert]

While working on some features preparing the deb packages and, I've done some minor housekeeping tasks:

• Removed old tests

All of the tests under tests/ seemed to be for a much older version of Keter. If these are still valid tests I will be happy to put them back. My goal is to implement some new tests where possible and these were a bit confusing for me as I started by trying to run them

• moved bundles/ to incoming/

I can't actually get the bundles tests working. I'm still looking into making it work with the current set of tests.

Worth noting that the documentation states that quoting wildcards "app.*.domain.net" is necessary and the bundles don't quote their host names.

• Documentation fixes in README.
• Remove some redundant language extensions
• Add ghc 7.6 to travis build. I use a few older versions of ghc for various building tasks so would like some validation.
• add systemd service file (this is still in the works).

I'm not sure why the build is failing and I'm having trouble recreating failure locally:

wai-extra-3.0.4.1 (new package)

cabal: The following packages are likely to be broken by the reinstalls:

ghc-7.8.3
Cabal-1.18.1.3

Use --force-reinstalls if you want to install anyway.
The command "eval cabal install --only-dependencies --enable-tests" failed. Retrying, 3 of 3.

Looks great, thank you!
