Add .travis.yml and reconfigure release process

- travis-ci used to publish binaries to the GitHub releases tab on new release
- Will also publish .deb and .rpm packages
- Haven't gotten the checksums file to work yet
- OSX x86 also isn't working
- No longer using goreleaser to publish binaries
    - didn't support cgo cross compilation which made things difficult
- Remove obsolete Makefile
