Removed FocusChanged and get back to old logic for SelectedPane

[anovik]

Due to conflict of FocusChanged with Avalonia message boxes.

Fix for #102

[anovik]

@Diaskhan could you please review the PR, it partly reverts your logic but according to my testing all keys/tabs are still working correctly. But now we can delete items without switching to the second pane in process.

[Diaskhan]

I wouldn recomedned to revert that,
Could U descibe bug in details ?
The problem, with hotkeys, it that commands Enter,Backspace, Delete must be binded careffuly,

SmartCommander/src/SmartCommander/Views/FilesPane.axaml.cs

Line 57 in a2c2dcd

public void dataGrid_PreviewKeyDown(object? sender, KeyEventArgs e)

FilePane could be in Editing mode, when we are renaming files (in place editor).

Only way to procces that key correctly is to use dataGrid_PreviewKeyDown and
PaneDataGrid.AddHandler(KeyDownEvent, dataGrid_PreviewKeyDown, RoutingStrategies.Tunnel);

In general when bind command they Events wont be sended to inplace editor! Buggy Avalonia

The best option to make focus on Delete Widow, when we are opennin them!
I fixed behaviour of Modal window for Configuration, but maybe for other Is still persists!

[Diaskhan]

Better solution is to refactor fix behaviour of

SmartCommander/src/SmartCommander/ViewModels/MainWindowViewModel.cs

Line 600 in a2c2dcd

public void Delete()

when we hit MessageBox, focus is still on mainwindow!

in TC focus is default on Yes button

[anovik]

I know the focus problem in message boxes for Avalonia, it seems there is no way for now to set focus correctly.
