LRDOCS-495. Explicitly noted that the src/main/java directory is created
upon creation of the portlet plugin project using Maven. Also fixed
indentation problem in the Maven/Theme/Anatomy. It appeared that the
css, js, images, and template folders should be under src/main/webapp,
when in the text we say they should be one level higher (src/main/js,
for instance).
