Save slot limits and autosave interval

Four sliders in a new 'Saving (quality of life)' section of the Player tab: manual, quick and autosave slot limits (SaveLoadVariables.cfg SavesLimit, vanilla 31/3/10) and the autosave interval in minutes (AutoSaveVariables.cfg AutoSaveIntervalTime, vanilla 600 s). Both files are plain cfg like CoreVariables, so they are extracted as-is and patched as <Name>.cfg_patch_<Mod>.cfg; the cache schema moves to 17. Values are read live and only deviations are written. Not play-tested.
