Good deal of Code Cleanup for the maintab

Some cleanup was needed in the MainTab code for ages,
now the Edition / Cancel / Ok of the Notes tab is
way more intuitive on the code level.

This is needed to support multidive edition on the
Cylinders and Weigths too, since it's a bit more
complicated, I didn't want to start with a Spaguetti
Code.
