This reverts commit 31d935254b3156429958bb6c5407a106456e9162.
Now that we are adding kali purple themes I've noticed that breeze qt
theme doens't follow the color-palette everywhere. In some cases it
still shows the blue highlight color.
Plus installing it in Xfce as an example takes 40MiB (unpacked)
This reverts commit 4a6d8f422ecbcadb32f54bfa7daacfe59df85beb.
Adding a dependency to `kde-style-breeze` pulls in around 35 new packages,
for an additional size of 40 MB (unpacked). It's basically a part of the
KDE stack that is installed. Not nice for users who don't run KDE.
