url rewrite in proxy module broken because of node-http-proxy version bump - never specify ^ in dependencies

[Nowaker]

http-master wasn't usable because of ^ being used with http-proxy.

@RushPL 0.7.13 should be usable, please release.

Please review other versions in package.json and replace ^ with fixed versions that are proven working OK with http-master. Having ^ is too risky. Semver is a utopian idea - just like checked exceptions in Java. :/

I heard you like iframes... ;)

Once all ^ are removed, we just need to have a look at Gemnasium from time to time and manually bump the dependencies followed by thorough testing.

Worth noting unit tests didn't catch the problem. Url rewriting was broken:

"jira.atlashost.eu/test/*": "localhost:10000/test/[1]"
=> GET /test/index.html/test/index.html HTTP/1.1

Some additional tests for url rewrite is needed.
