shed v0.3.0 - a generic session process for x11 and wayland

due to how generic shed was designed it is also an implementation of user services completely independent from any single init system, to be as generic as possible shed is written in mostly posix compliant shell with only 1 function making use of a linux kernel exclusive feature, the architecture takes some inspiration from the likes of sysvinit but takes no code from it whatsoever, the github repo is: https://github.com/eylles/shed
