Building without a Makefile (on Windows)

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!
