Recent formula history

David Hall Travis-CI uses brew test-bot Copied .travis.yml from brew-tap-new script. This should make for quicker testing, because only the edited formula is tested. Also moved formulae to Formula folder.

David Hall Style changes
Enrico Bothmann fastnlo:, mcgrid: 2.0.0
Dmitry Kalinkin replace sha1 with sha256 (fixes travis tests)
