add mapper 29 and preliminary mapper 30 support (#8225)
New working software list additions ----------------------------------- 2A03Puritans [rainwarrior] E.T. [KHAN] Glider [anonymous] * mapper 29: support should be complete but there are few if any other homebrew roms to test against * mapper 30: only supports the most basic board that doesn't use flashable memory - tested on a dozen or so roms, all working * add a game each for mappers 29 (Glider), 30 (E.T.), and 31 (2A03Puritans) so there is something in the software lists to actually test against. Glider is discontinued by manufacture, the other two are freely available from their authors. * various naming clean ups, like BTL- prefixes for things that are not bootlegs
