  Fix Travis GCC warnings for f2b31ba082e1

This also removes a bunch of unnecessary CVideo arguments from various savegame functions that
emerged as I cleaned up the unused parameters. savegame::save_game did take a CVideo pointer
that did look like it was intended to be a sort of do-show-dialog flag, but since that parameter
was never passed as null, I removed it.
