Installer script and cleanup
* Stop users from saving config with invalid download directory * Added additional sanity for email checking * Add installer script * Update cronwrapper to work with installer script * Add AUTOUPDATE to default config * Read /etc/plexupdate.conf before other configs, if available * Use dnf on newer redhat systems * Only use plexupdate.conf or --config * Give existing users explaination as to why plexupdate.sh failed * Removed references to .plexupdate * Warn users that .plexupdate is going away * Offer to import settings in ~/.plexupdate.conf in installer (if they exist) * Only show AUTOSTART warning if AUTOINSTALL is enabled * Change default download directory to /tmp * Warn users to run the installer as sudo * Remove VAR_CL logic in favor of checking config before getopt run * Use sha1sum for version check and auto-fix git permissions on exit * Skip update check if AUTOUPDATE is enabled * Fix permissions for all files, not just .git * Don't enable -P in installer if we know it won't work
