Remove deprecated Code

[roy-silveira]

The CMSFilter.addExclude(), removeExclude() methods are deprecated. Could they be removed from the plugin seeds to help clean all of them up.

Example:

plugin-seeds/OSGi/com.dotcms.servlet/src/main/java/com/dotmarketing/osgi/servlet/Activator.java

Line 47 in 4cfc980

CMSFilter.addExclude( "/app/helloworld" );

Thank you,
Roy
