New RA config scripts

batocera-settings-set is finally not compatible for RA config (spaces are required before and after the "=")

We will use CrossMix own script finally : get_ra_cfg.sh and set_ra_cfg.sh
Usage:
set_ra_cfg.sh <config_file> <key1> <value1> [<key2> <value2> ...]
get_ra_cfg.sh <config_file> <key>
