Some Windows Support

[siennathesane]

Starts to fix #103. Not sure what full support would look like, but this is a start. In retrospect, I likely should've branched instead of doing this on master.

[siennathesane]

It's not perfect, but it's a good starting place for now.

[senorprogrammer]

I have no way to test this out. It would be great to have this code-reviewed and corroborated by a few other people.

[siennathesane]

Sure. There's no rush.

[senorprogrammer]

One question I'm not clear on from the code: how does it know which platform to load? For example, with dns_darwin.go and dns_windows.go, how does it know which one to use?

[senorprogrammer]

Also, could you rebase against master for me? Once I understand this a bit better and the rebase is done, I'll merge it in. Thanks!

[siennathesane]

@senorprogrammer when you do go build, the compiler will build the binary based off the target OS. So if your GOOS is darwin, which is the default for macos, it will build anything with the *_darwin.go* flags. You can find more information on golang build tags here - I just use the *_windows.go build tag since they are nearly identical and it's easier for us humans to understand. :)

[senorprogrammer]

Awesome. Thank you for the explanation. If you're able to rebase this against master, I'll merge it in.

[senorprogrammer]

Just touching base. No hurry, when you're able to rebase this against master, I'll merge it right in.

[siennathesane]

Should be good now. I really meant to do this on a branch. Next time I will do so.

[siennathesane]

Also, feel free to ping me for Windows stuff down the road since that's my domain. It's a nifty tool and would love to see better support for it.

Travis is failing because you have go get ./... && go get github.com/go-test/deep && go test -v github.com/senorprogrammer/wtf/wtf_tests as one command and I don't know which part of it is failing, so I can't fix my builds until you're able to fix Travis.

[senorprogrammer]

The following errors:

18.51s$ go get ./... && go get github.com/go-test/deep && go test -v github.com/senorprogrammer/wtf/wtf_tests

TravisCI runs on Linux and the changes you've made are now Mac & Windows-only.

Take a look at the way power/battery.go and power/batter_linux.go are defined at the top of the file. This might be fixed by adding // +build !windows and // +build windows to the respected files.

In the meantime I'll look into getting TravisCI to present useful error messages somehow.

[siennathesane]

I think it would be good to cross-compile, but I'm not sure what that would look like on Travis.

[senorprogrammer]

Got it working. Thanks for making this PR!
