Set Inspector loads as a modal dialog

[patrickhuber]

Describe the bug
The set inspector loads as a modal dialog. This means you can't modify your build while inspecting sets.

MidsReborn/MidsReborn/Forms/frmMain.cs

Line 6602 in edc3320

setFinder.ShowDialog(this);

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Windows' menu item
2. Click on 'Set Inspector'
3. Try to click on the main window

Expected behavior
When using set inspector, we should be able to modify our build by clicking in the main window. I think using the Show method would be a better option https://learn.microsoft.com/en-us/dotnet/api/system.windows.forms.form.show?view=windowsdesktop-8.0
