Note: I'm trying to consistently leave a comma after the last item in each vertically formatted python list, so that when someone with less python knowledge wants to add something to the list and does it the "lazy way" by just copying the last line, pasting it on the end and editing it to add a new item, they won't cause the "missing comma" python error too easily. Having a comma on the very end of the list with no element after it doesn't seem to cause any harm or python errors. And you can copy/paste the last item as many times as you want without getting into trouble.
Just doing some sweeping up and prettifying. Main thing is adding the PCManFM fork, PCManFM-Qt to the overrides block for PCManFM. Working on the Nautilus variant reminded me.
Zorin OS uses Nautilus as default file manager, but its WM_CLASS is shortened to "nautilus" instead of the original "org.gnome.nautilus". So we have to add that to the list (and also to the overrides for Nautilus).
2021-04-05 updated version of Finder mods, supporting common Linux file managers:
```
#
# Caja File Browser (MATE file manager, fork of Nautilus)
# DDE File Manager (Deepin Linux file manager)
# Dolphin (KDE file manager)
# Nautilus (GNOME file manager, may be named "Files")
# Nemo (Cinnamon file manager, fork of Nautilus, may be named "Files")
# Pantheon Files (elementary OS file manager, may be named "Files")
# PCManFM (LXDE file manager)
# PCManFM-Qt (LXQt file manager)
# SpaceFM (Fork of PCManFM file manager)
# Thunar File Manager (Xfce file manager)
#
```
This adds support for the Deepin Linux default file manager, and some rearranging/code clarification improvements on the previous iteration. Closing PR #450 in favor of this update.
Install will fail (GUI window will not appear) on Manjaro unless system is fully updated first. This patch asks users to verify that they've run "sudo pacman -Syu" before attempting install.
Failure is possibly related to the GLIB error mentioned later in the install script. Not certain. But a full update always got Manjaro to finally show the GUI installer window.
