Yes I hate myself for creating this, but this is basically a fork of gnome-screensaver which is completely dead, and we need a drop-in replacement of gnome-screensaver with fixed bugs to use for Budgie.
Upstream previously indicated the only way to go is a fork, they're not planning on taking patches.
TL;DR Emergency fork to hold up Budgie 10, we'll do something less insane when it comes to Budgie 11.
The overwhelming majority of the patches are ported from Ubuntu's package-fork of gnome-screensaver to allow a simple drop-in replacement for the gnome-screensaver package.
UNLESS ANYONE WANTS THIS AS A PACKAGE, WE'LL JUST APPLY THE PATCHES BACK ON TOP OF OUR OWN gnome-screensaver PACKAGE
