This commit overhauls the repository structure such that it separates
the project into multiple repositories, one for each subproject. This
repository will be moved to the AeroShell group, and most importantly,
the installation method changes from locally installed modifications, to
CMake-based installation, in preparation for AUR packages, and possibly
packages for other distros.
Migration details are in INSTALL.md, which are highly recommended, if
not required to uninstall any old instance of AeroThemePlasma.
Note that this only works if using ATP's panel, SevenStart and
SevenTasks. Additionally, SevenStart and SevenTasks must be on the same
panel in order for this to work, as SevenStart will attempt to pin an
application to the first instance of SevenTasks it finds.
Fixed issues with apps that don't have a thumbnail
Group thumbnails should now display with the correct height
Improved slide animation (X11 only)
Hopefully fixed plasmashell crashes with the group thumbnails under Wayland
