UI: Add list item widget w/ visibility checkbox
This is used to allow the user to temporarily disable sources/filters. For each item in the list box, it displays a visibility checkbox (with eye icon) that the user can click to disable/re-enable sources or filters. I did not end up using the Qt::ItemIsUserCheckable flag with the list items for a few reasons: - We could not style the checkbox indicator without qss screwing up other parts of the list widget style on certain operating systems - We could not get the icon to properly invert on active selection like the text does on mac/linux, which made it look strange - Clicking the checkbox too fast would cause it to signal a double-click on the icon, opening the properties for a source in the source list
