Update Installer.sh

Added check for compatible Pi's

Added check if Pi 4 but a 2GB or higher model enable mounting /tmp to RAM.
If model is a Pi 4 1GB, 3B of 3B+ RAM mounting /tmp is disabled automaticly.

Added check if Pi 4 but a 2GB or higher model set Log2Ram to 256MB of storage space in RAM.
Otherwise keep it to it's default of 128MB.

Added check if not a Pi 4 series set CPU power to performance so the older architectures can keep up.
Otherwise set CPU power to conservative since the Pi 4's have a newer more effecient and powerfull architecture.
