Recommended directory structure

[kdallas]

For your review @PhonicUK

Recommendation for adopting the following directories to match core/production:
Fonts
Images
Scripts
Themes
... the latter "Themes" could later be split into "Less" & "CSS" with minor refactoring.

The image file naming is consistently named, but can also be refactored to accommodate a more defined set of rules.

Actually I'm thinking more along the lines of having each theme have its own folder, and it can contain whatever fonts/scripts/images it needs?

[kdallas]

Great idea @PhonicUK -- I like that, each being in a packaged up "bundle" essentially. Then only adding the sub-folders each actually needs (or no sub-folders at all I suppose). You could also have a root info.json or markdown file in each theme folder, instead of placing that in the .css itself. Would you like me to have a crack at this and produce another PR?

[PhonicUK]

That would be awesome, yes :) I'll drop this PR. I'd be perfectly happy with an info.json file in each directory with the theme information - but the reason I wanted to put it as metadata in the less/css itself was for backwards compatibility, but I suppose it's not a huge deal.
