Remove JDF references from TicketMonster

Actually ticket-monster still making references for JDF on its home.html page.

It would be nice to replace "A JDF showcase" and its logo and link to "A JBossDeveloper showcase.

The "Learn with it" section link should also point to http://www.jboss.org/ticket-monster/

The link should point to http://www.jboss.org/ticket-monster/ and the http://ticketmonster-jdf.rhcloud.com/ should also be updated as well.

The logo should be a reduced version of http://www.redhat.com/cms/public/jbossDeveloper-475x228.jpg

Wildfly branch should also be updated.
