A new spring, a new version!

CHANGES with respect to V2.2: V2.2 had some residual debug info left showing
after pressing 'Shift'. Removed. 
No further changes to functionality.

This version is sorted by assign name.
All assigns are now shown against a back ground of alternating colour.
For supposed enhanced readabillity.

When unpacking you might want to unpack it in one directory; I did not manage to
get that automated, so...

After unpacking it can be used immediately, no installation required, no assigns
to be made (sic!), no hairpulling situations. Just double-click its extremely
ugly, but home made, icon.

Oh, and before I forget: it is now compiled against newlib, which makes for a
substantial DECREASE of size.

Have fun!
