Added convenient shortcut for HEAD

[dahankzter]

I just thought it would be nice to be able to write r.HEAD.

I am not sure if my little change is correct wrt the underlying aech but it seems to work.

Is it possible for you to take this? It is not crucial of course but nice to have the corresponding HTTP methods. I guess OPTIONS and TRACE could be added although CONNECT seems far fetched.

I'm not sure whether more shortcuts like this should be added or not.

On the one hand this is not much code and does not really bloat the package. Moreover it could make the code a bit more consistent for some users, since they don't need to use r.Handle("HEAD", path, handle) and so on for some routes, while using shortcuts like r.GET(path, handle) for all other routes.

On the other hand the shortcuts are meant for really often used request methods only. I think that would be the 5 currently included ones. Where should we draw the line, if we also add a shortcut for HEAD? Then OPTIONS would also be a must, I think.

I'd appreciate comments from any other user of this packages (Hello, repository watchers 😉 ).
How do you use this package? Do you use request methods like HEAD and OPTIONS a lot?

[dahankzter]

Personally I would of course like to add HEAD since I tend to use it at least from time to time when it makes sense.

OPTIONS however I have never used nor even seen used in any project. It could be added for completeness but other than that I don't think there is a compelling reason to add OPTIONS.

[dahankzter]

You didn't take it? It was very little code for a nice symmetry in the operations.

OPTIONS is used with CORS: http://www.w3.org/TR/cors/
