Fix importing files with dots

[eppsilon]

This PR was forked from @JohnAlbin's branch from #19. It would probably be best to merge that before reviewing this, or you can just look at commit 8025bbc.

lgtm... Any movement on this.

Merge conflicts :(

I updated the branch with the following changes:

• Rebased atop this repo's master
• Removed .only call in tests file - that was the only test being run (!!!)
• Disabled some eslint warnings about code that was already there

Will this get merged?

[eppsilon]

I created this PR in November and rebased it in February, so...not looking likely. @Snugug ?

This repos seems to be unmaintained, hence we create a fork and republished it on npm as @axa-ch/node-sass-import-once
In case you need this still to be merged, just open a PR at https://github.com/axa-ch/node-sass-import-once ... we will be happy to improve this valueable piece of code 😃
