Add two new portals instead of Brinstar save rooms

[PJBoy]

As suggested by TarThoron. Change door transitions to save rooms that are guarded by bomb passages: Desert palace back door -> Pink Brinstar mainstreet (from save room) Death Mountain moldorm cave -> Kraid's lair kihunter room (from save room)

Those bomb passages lead to softlock if destroyed with last power bomb and without bombs collected. No change in logic required.

Firstly, I think this will eventually be changed with in-SM softlock patches. Secondly, if I get this right, Desert would indeed simply lead you to Z3 first sphere (assuming walking in returns you to the save room, not the DP dungeon). But exiting through a cave entrance into DM is not first sphere, it would circumvent flute or glove+lamp (and possibly also hookshot or mirror+hammer depending on which exact entrance this is), right?

[tewtal]

Exiting from Kraid's lair into DM is fine since you would be able to use the regular Norfair DM portal in that case anyway.

Hm, yeah I guess that's true. Didn't think through all the possibilities due to my first point.
