Issue description

I have two folders with identical files - about 50 files in total. If I drag all the files from folder A to B, I get a popup asking me to confirm the overwrite. Problem is the confirmation window lists all the file names to be overwritten and because there's so many, I can't actually see the confirm or cancel buttons at the bottom of the popup. The popup isn't scrollable and I can't resize it to make it smaller vertically.

Steps to reproduce

Have a folder 'foo' with 50 files in it. Doesn't matter what the files are. Empty resources will work. Duplicate the folder and name the duplicate 'bar'. In the FileSystem drag all the files in 'foo' into 'bar'.

AcceptDialog does not support label scrolling. Label doesn't support either (RichTextLabel does, but it can't be used instead of Label as it breaks compatibility). I'm not sure which solution is more correct:

1. Add scrolling support to the Label.
2. Add scrolling support to AcceptDialog (wrap label in ScrollContainer).
3. Use custom dialog in FileSystemDock.

I doubt between the first and second option.

We don't need any custom dialog. You can just add a ScrollContainer to a dialog and a Label, and use it instead of the dialog text. There's a chance this dialog already uses a "custom" label.

I think scrolling can be useful in user code as well (as a property of AcceptDialog or Label).
