[tycho-user] New Tycho-Pomless wiki page
Because i noticed there is no real documentation about all the cool
features of tycho-pomless regardless of some blog-posts and
release-notes I started a first (very basic) wiki-page to describe it
a little bit more.
I also added a FAQ section to add common questions. It currently is not
so detailed but I hope to find time to enhance it over time, would be
good if someone could review it or give feedback what might be missing.
