foss-artist-install_v0.0.1

This is the very first version of the foss artist install trunk.

Right now this is just for KRITA, but other apps will follow this new system.

The goal is to contain every useful art software in one place to allow specially curated VFX suite for Fedora based Linux users.
First we're starting with Krita and added some features that photoshop users will find handy from ACLY.

Tested on Nobara 42
