Add rake-compiler-dock for building Windows binary gems.

rake-compiler-dock makes building Windows gems faster and with little to no setup
compared to rake-compiler-dev-box. A simple 'rake gem:windows' should be enough.

It is still possible to use a native cross build environment or rake-compiler-dev-box.
