Thanks, everyone!

Here is a new version: HeadShake.20170105.Beta
Don't forget to remove previous version with JSGME before installing the new one.

Added roll inertia. I tried to make the effect appear stronger when roll starts but mostly realign a few moments later. Not sure how well it looks.

Added experimental mouse look in cockpit view. Use mouse wheel to zoom. Mouse speed is not adjustable yet.
Hold ALT to get mouse cursor back. The view automatically recenters if you don't move mouse for 5 seconds.

Also fixed some bugs, including bombsight movement - it should be fixed (literally) now.

This is still in "beta" state, but seems to work well. Comments are welcome
