Main changes:
- Switched to using `go-bindata` in place of `scripts/embed-static.sh`.
- Support for building Prometheus without a `Makefile`.
- Minor typo fix to make Prometheus build on Windows (without Makefiles).
Please note that this does not mean that prometheus will work on Windows.
There are still failing tests!
The route package is a thin wrapper around github.com/julienschmidt/httprouter.
It brings the interface back to http.Handler and embedds params in a context.
The new router comes with prefixing support.
