Add function to properly import gpg keys

[bastelfreak]

This is a rebase of #118

Fixes #116

Hi @linuxdan. I fixed the spec issues. The function was in the wrong directory. Can you add an acceptance test for this?

@bastelfreak
Sure, but I do not know how.
Might you have a link or three describing how to write one ?

@dhoppe I could never get past Travis.
If you can get my function into the master branch, I would be eternally grateful.

TravisCI fails for two reasons. First the variable $path contains a / and the Rspec tests have to be adjusted.
