Option to turn off ALL savestate compression, disable status message when making a savestate with LUA

[GoogleCodeExporter]

Necessary in order to create a rewind script that won't slow everything
down to a crawl. 
It's nice that you can actually lower the compression but the emulator
still lags a lot when saving, nowadays HD space is rarely a problem and the
SNES ram is fairly small anyway, it really makes no sense, I think
uncompressed saves should be default.

Also everytime you save using LUA there's an annoying "SAVED SNLUAXXX"
screen message that can't be turned off, which is redundant since you could
just write an extra line of code if you really wanted confirmation.

Suggested fix would not actually fix the problem. Snes9x savestates are 
extremely slow (compared to, say, Gens) and the saving/loading code might need 
to be completely rewritten to fix that. The default compression settings are 
not the main thing making them slow.
