Theme recalbox-backport created for this build

[fonic]

I created the theme recalbox-backport, which essentially is a backport of the current Recalbox theme recalbox-next to the original theming engine of EmulationStation (i.e. it works without the custom ES patches used by Recalbox) plus some tweaks and additional content.

It works perfectly with your build. I'd greatly appreciate it if you could mention the theme in the README so people can find it. I put A LOT of work into this and I'd hate to be the only one using it ;)
