* Swap out gopass dependency Remove github.com/mewbak/gopass in favor of github.com/howeyc/gopass * Add Windows to Makefile and build_release Added Windows/386 and Windows/amd64 to the Makefile. Some minor changes needed to be made to build_release to give the windows binary the ".exe" extension. * Makefile: remove windows/amd64
