DELTASPIKE-384 improved creation of the view-config node-list

 thx to Richard DiCroce
Set WebProfileCategory for tests including a persistence unit. Can be removed once we have a proper setup for Java SE profiles (mainly OWB).
DELTASPIKE-388 Finished the creation of the factory, setup tests to be able to run in SE mode.
updated developer section
DELTASPIKE-390 support for (optional) custom ConfigPreProcessor for @ViewMetaData
DELTASPIKE-390 custom ConfigPreProcessor test
DELTASPIKE-60 remove @author
DELTASPIKE-392: Document proper EM-producer
DELTASPIKE-391 Add QueryBuilder beans to application scope - looks like they get recreated otherwise over an Instance<> lookup.
