[jboss-as7-dev] JBoss AS 7 Getting Started Guide for developers + Docs repo

In preparation for the AS7 release, I've written an getting started guide for developers for AS 7. The focus of this guide is on the standalone mode of JBoss AS 7, and the EE 6 programming model, and consequently how you can write some simple apps using AS 7. It also includes instructions for using the AS7/EE 6 archetype that we will release alongside the guide. I've added the guide + quickstart samples that live alongside it to the docs repo on github - https://github.com/jbossas/docs. This repo also includes a a distro script for building a zip, and some basic development instructions for quickstarts in the README. I just want to emphasise though, that the quickstarts are aimed at users, and so aim to be as simple as possible - we've elminated as many xml files as possible, made the pom as simple as possible etc. This (especially in the pom) means that things are quite as optimised as they might be (e.g. no shared parent in the quickstart poms). This is 100% intentional - the aim here is to have something people can copy and change easily - a shared parent isn't good for this!. Anyway, please review, and add any other guides as you wish :-) Pete
