Ok, so firstly, I'll admit that I never tested touch actually working on the previous release.  Hopefully I will at some point.  Nevertheless I realised it would have had a bug, so fixed that.  Maybe.  It's still not tested.

Anyway, on to the new stuff.  For this release I have:

1. changed the way the ship chases to make it less aggressive.

2. tweaked the placement of the help text

3. added a new soft waves setting, which is to become part of a more managed wave system,  it's off for this release mind...

Here it is: v6
