Support subfolders in layouts the same way they are supported in partials

for v2.0

@gakimball Any chance we can get that any time soon? (in the v2 branch?)

I can probably get to it in the next few days. With the spare time I have I've been working on #143, which refactors how all the template/partial/helper loading works.

If you'd like to implement it before then, I'd take a PR.

Thanks @gakimball no much spare time these days.. can you point out the similar PR for the partials.. just to get an idea?

Here's where it happens for partials: https://github.com/zurb/panini/blob/8d5a66701f299c5040b41e24165324f02ed94c11/engines/handlebars.js#L49

You can see that the name is a calculated path based on the project root. Whereas, if you go up a few lines, where layouts are created, it just takes the basename, which means it's always just the name of the folder. Basically you're gonna copy the path calculation code from partials over to layouts.
