Moved MM mission settings parameters into new DB table called Meta_Battlefield_Settings; also updated MP-OptionsScreen.php accordingly. Also enabled support for $PLAYABILITY_EXCLUSIONS_LIST whereby specific soldier types can be disabled from human play. The excluded types are list as strings delimited by "|", e.g. "LIB_GER_gun_unterofficer|LIB_GER_rifleman" up to a length of 512 characters.
