added support to consider all platform Java sdk classes and public
function exports - for dependency satusfaction

Also fixed a bug in BundleAnalyser when the plugin being analysed is a
directory and the   code was doing wrong file path name comparison to
check if an internal jar was in the bundle classpath and also when
finding out where the manifest file was.
javadoc update. 



[[Will consider moving javadoc to a separate working directory.    ]]]]
