Duplicated links at API webpage

[jeandersonbc]

When I opened http://joaoarthurbm.github.io/designwizard/doc/ I noticed that in the "all classes" section, links are duplicated.

On my forked version, I didn't get duplicates http://jeandersonbc.github.io/designwizard/doc/

Maybe running javadoc to generate the documentation again might be sufficient to fix it.
