[ee4j-pmc] Formatter Rules Configs

["Markus KARG" <markus@xxxxxxxxxxxxxxx>]

There are recommendations for code style on https://github.com/eclipse-ee4j/ee4j/wiki/Code-Conventions and I am pretty sure there are people having set up ready-to-use formatter rules configs for Netbeans and Eclipse IDEs. So I would be happy to find them uploaded into the WIKI to make it easier to contribute to EE4J subprojects. I'm writing this to the PMC because I assume that rules where decided by you and you already had such files at hand when deciding it. :-)
