Test with shellcheck

[JonasGroeger]

$ shellcheck bullet-train.zsh-theme 

In bullet-train.zsh-theme line 423:
  if [[ (-f *.go(#qN) || -d Godeps || -f glide.yaml) ]]; then
  ^-- SC1009: The mentioned parser error was in this if expression.
     ^-- SC1073: Couldn't parse this test expression.
                ^-- SC1036: '(' is invalid here. Did you forget to escape it?
                ^-- SC1072: Expected "\\)". Fix any mentioned problems and try again.

This is the only thing. Not sure if this is an error.

I'm thinking about doing it on an automatic way on Travis CI, like travis-ci/apt-package-safelist#376
