Initial implementation of m2e connector for jspc-m-p.
m2e connector for jspc-m-p now only copies web.xml.
Eclipse has its own JSP validator, there is no need to generate Java
sources. But in projects with jspc-m-p the m-war-p is usually configured
to use web.xml modified by jspc-m-p, so we copy it.
Removed inexistent module from the root pom.xml.
Added connector for jspc-m-p to the update site.
Added configurator for jspc-m-p 2.
Moved common build participant implementation to base class.
Improved unit tests.
