Qt6 is out now.

Issue #10 "Mass deletes from Playlists super slow" made a major improvement in mass delete performance, however there are still some related issues. In particular, if e.g. you do this:

1. Sort the Library view on one of the columns.
2. Select all and Copy.
3. Paste into "Now Playing".
4. Select all in "Now Playing".
5. Deselect a few items.
6. Delete.

Even though the original Delete selection in 4&5 consists of a few contiguous ranges in proxy-space, it appears that Qt ends up breaking this up into many single-row removes by the time it gets to the underlying model. This of course makes things slow again.

Not sure if this is ultimately completely solvable, but something like adding a step where we "re-contiguize" the selections in underlying-model-space might be beneficial.

Think it's a status connection problem.

Looks O(n2). Appears that the delete is ultimately always deleting the first row, and then the view and selection models update and look at all remaining rows, taking care of destroying performance.

Idea would be to alternate between the original song and the corresponding Weird Al parody. That would be awesome.

E.g.:

[2018-01-07T19:59:58.198 DEBUG] LibraryModel::data:177 - Returning pointer to item with Url: QUrl("file:///Z:/U2/1998 - The Best of 1980–1990 - cd 1 of 2/U2 - The Best of 1980–1990 - cd 1 of 2.flac")

CMake has gotten a lot better since I originally worked up the CMakeLists.txt's for this project. Update them to modern CMake standards, which should simplify them, possibly significantly.
