Add SBP langage

I used Prism on [http://sbp.selfbuild.fr/](http://sbp.selfbuild.fr/) and extended PHP Prism component to handle SBP, the langage this website presents (not yet translated), SBP is an open-source langage that adds syntaxic sugar to PHP. So I propose in this pull request the code I used to display SBP in Prism.
Here is the SBP repository:
