Updated Documentation

First cut to update documentation to reflect maven builds.

Note: All documentation needs reviewed as some notes about builds
appears to have changed some time ago and was unsure how to address.
This only addresses general maven build & already present was the
deployment to maven central.  It does not go into maven site generation
or other profiles yet.
More manifest items & moved war plugin to parent

Added additional information to poms so users can easily determine what
version of the jdk is expected to be used.  This is more important since
tomcat8 requires java7.
ISO-8859-1 to UTF-8 - web.xml

Updated all web.xml files to use universal character encoding rather
than legacy ISO-8859-1.
waffle-filter pom - fixed

Corrected issues in waffle filter pom preventing it from working
properly.  Eclipse had issues importing in the form it was.  Also
removed information regarding the prior non maven layout.  Final war
build will no longer contain version number so it is easier to drop and
deploy for users testing.
