In order to prevent `nix-store --gc` from removing too much I've:
- Added the `keep-outputs = true` setting to `nix/nix.conf`
- Fixed `nix/scripts/gcroots.sh` to make symlinks in `/nix/var/nix/gcroots`
- Made `nix/scripts/build.sh` and `nix/scripts/shell.sh` use it
This way when running `make nix-gc` most recently used shells and built
derivations won't be removed along with their dependencies.

Changes:
- Add missing lazy assignment for OS_NAME, fixes double Nix shells
- Moved `scripts/add-nix-gcroots.sh` to `nix/scripts/gcroots.sh`
- Moved Nix package manager setup to `nix/scripts/setup.sh`
- Created `nix/scripts/source.sh` to reuse in all Nix scripts
- Created `STARTING_GUIDE.md` with instructions for contributors
- Created `scripts/colors.sh` for definition of shell colors
- Removed `scripts/setup` in favor of `nix/scripts/setup.sh`
- Removed all of `scripts/lib` since it was useless
