Update JBoss Tools features page to better promote Fuse Tooling (not in Integration Stack anymore)

Once Fuse Tooling is in JBT, we'll have to update http://tools.jboss.org/features/index.html to reflect that fact.

See https://github.com/jbosstools/jbosstools-website/blob/master/features/apachecamel.adoc for source of the page to update.
