Fixes #363, refs #365. Splitted HorizontalDock::timebaseChanged handler.

Windows 11-targeted fix as it probably works on other platforms.

Splitted HorizontalDock::timebaseChanged event handler from doing operations on dsoControl and dsoWidget in the same callback. Now there are two callback and each uses the QWidget it operates on.

Now we can change horizontal time-base:

Without the fix we encounter such issue:

A big thank you to @nseam! I checked this issue so many times but didn't see the wood for the trees. Your easy solution is highly appreciated! Please check also if the win binary from the latest unstable release is working correctly. It is built with the MinGW compiler suite while your setup uses MSVC++ - but it shouldn't make such a difference.

I've checked the binaries and it is no longer crashing, yippie!

I knew that is has something to do with accessing widget that was not a part of connect()'s target. Looks like Qt stops other threads from writing only to connect()'s target's QWidget, so we need to split event handlers if wants to write to other widgets.

I will later (just for test) try to pass parent widget as the target to connect() so, if Qt locks all the widget's hierarchy down, will allow us to access both widgets in the same handler. I will get back with info if that worked.

Thanks @Ho-Ro for maintaining the software! My 6022 just arrived so I will try the software in this evening!

Just a note: when I was clicking all the buttons in Demo mode some exception occurred, but didn't yet found which one did that. However, if something will error, I will try to fix it and make a PR.

I'm also curious how many people uses this software :-)
