The PX4BuildBot extracted the comments from the lines following
the class line which says "Plane" as the class. To avoid the
confusion for the bot I moved the comment further down.

 * The X-UAV Mini Talon airframe with the new type Plane V-Tail uses the new AAVVTWFF_vtail mixer.
The new mixer is derived from the AAVVTWFF mixer and is a generic V-Tail mixer. I left the flaps and wheel although there are no flaps and wheels on the mini talon to keep it generic. The airframe configuration is derived from the Albatross A-Tail.

The typhoon has a 6011_typhoon_h480.post script that got matched as well.
Now we exclude all files that contain a dot (apparently it's not so easy
to do generic pattern matching in a portable way, but this works).
