Add capability of loading and saving combinations to the Combination Setter panel.

[oleg68]

Now exporting and importing combinations are possible only with a menu.

It would be more convinient to do it with special controls in the Combination Setter panel. Hauprtwerk already has a similar capability.

@larspalo @rousseldenis

I'm trying to add more controls to the sequencer panel.

What variant is better:

or

?

[larspalo]

@oleg68 The first one. Not the green icons please.

Why not take the opportunity to modernize the interface?

For example

[larspalo]

Becacuse the icons doesn't actually say what the buttons are doing. An arrow right means what... Right? Whereas the text is immediately obvious to anyone that can read. Not to mention that the icons have a style that doesn't match the existing drawstop (buttons) at all.

[rousseldenis]

Yes I +1 for the first option too. To be more compliant with the current toolkit library, we should not break the user experience. Maybe in a soon future, doing a revamp of the whole toolkit should be done

[larspalo]

@rousseldenis In my opinion, if we want to modernize the built-in graphics, it should be done as new additional bitmaps (and using them inside GO by setting new defaults). But they should all be really thought through so that they will harmonize together in a coherent style.

[oleg68]

OK, let's choose the first variant. I'm finishing working on the issue now. The evaluation build is already abvailable at https://github.com/oleg68/GrandOrgue-official/actions/runs/4693356345 .

As soon I adjust the help, I'll open a PR with it.
