Doesn't handle multiple, similar, reference to the same file

See original issue here: ember-cli/broccoli-asset-rev#116

Given the input:

<img src="assets/images/picture.png"/>
<img src="/assets/images/picture.png"/>

And a fingerprint of https://mycdn.com/

The output is:

<img src="https://mycdn.com/assets/images/picture.png"/>
<img src="/https://mycdn.com/assets/images/picture.png"/>

(Note the incorrect slash at the start of the second URL.)

This can be avoided by using the exact same URLs everywhere in your source code. It would be nice, however, if the rewrite engine handled this automatically (eg a sort to process the longer replacements first?)

This seems to be very similar to the issue I reported. See: #63

I think it's a problem with the regex but I'm afraid to change the regex since I can not estimate if and how a change of this regex could break existing apps.
