Issue with doubble dots in dir names

[jcsrb]

For reasons beyond the scope of this ticket my project uses dir names that include .. and therefore path like /home/code/test/compare/master...jcsrb are possible and the way this module detects if the path is relative https://github.com/ember-cli/exists-sync/blob/master/index.js#L18 gives a false positive and causes broccoli-funnel which uses this module to fail

Preparing PR with failing test , will add ASAP

This project was created, because for a short term fs.existsSync was deprecated. That was changed, and it is not deprecated. So maybe in this project we should simply delegate back to fs.existsSync and call it a day.

broccolijs/broccoli-funnel#100 can just use fs.existSync directly now

[jcsrb]

thanks for the incredible fast response will switch that version of broccoli-funnel

[stefanpenner]

broccolijs/broccoli-funnel#100 merged and released as v2.0.1

I think we should still consider: #8 (comment) here, thoughts?
