This patch does the following:

• The content from the gh-pages branch is converted to AsciiDoc and copied to the docs directory in master
• A new profile is added to the parent pom to build the documentation. This profile is not executed during the normal build and has to be explicitly reqeusted
• It does not alter the current project web site content, it just stages the content needed to do so at some point in the future
• This is intended to get everything staged so we can test the creation of docs and website content before actually pushing it out to the public site

Code to create docs in geowave/target/site

# Build javadocs
mvn clean install javadoc:aggregate -DskipITs=true -DskipTests=true

# Build docs
mvn -P docs -pl docs clean install
