Release 0.1.0

This is the first release of ocf just to make it easier to try things out. Download the appropriate binary for your system, rename it to ocf, and try ocf -h, ocf push -h, etc.

It's quite likely that the Windows binary does not work properly since it shells out to oc instead of oc.exe. But, I'd prefer someone with access to a Windows machine try it out and help fix things before I just guess about what to do to make it work.
