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!
