copied doc-files folder contains svn meta files

I have included a png into src/main/javadoc/package/doc-files. Turned the appropriate switch on. Files lands in the jar, so does SVN meta files.

Reproduce with:
checkout http://svn.fckeditor.net/FCKeditor.Java/trunk/ r3582.
cd java-code
mvn

examine the javadoc jar and navigate to: net/fckeditor/connector/doc-files

I have scanned the source of the javadoc and subsequent plugins and default excludes for svn are applied.

Check the attached list.
