Fix LiveReload for asset subdirectories. Fixes #56.

[dcalhoun]

Jekyll's _config.yml exclude option does not allow for paths to subdirectories. In order to support LiveReload of asset subdirectories, this commit passes the _config.yml file the deepest directory for each asset type (e.g. – JavaScript, CSS, images, fonts). Fixes #56.

I'm reluctant to exclude all folders with the deepest directory — I suppose this is default Jekyll behavior, but it feels broken to me.

Did you try the globbing way: my/asset/dir/**/*? jekyll/jekyll#906 (comment) leads me to believe that might work.

(Thanks for the reference links, btw!)

[dcalhoun]

Yes, I did try nested globs. It did not work. The only alternative that I can think of is excluding the top-level directory for each asset type (e.g. - /assets/) rather than the deepest.

I believe this ultimately should really be fixed on Jekyll's side, but until that happens I think this is a good solution. For people who stick with your default top level asset directories, absolutely nothing would change. We are just expanding the capability of the generator.

[robwierzbowski]

Works just like you describe. Refined the exclude dir generation a little and merged.

Adding a little note to the readme as well. Pinged the Jekyll issue, hopefully we'll get a fix soon.

Thanks for the great issue report and PR.
