PSP issues about spelunky-psp

[dbeef]

Hey @jkulawik, thanks for reporting your findings and kind words,

You are correct with everything, just to respond to a few points:

• Circle to crouch (why isn't Dpad down used for this?) - I felt pressing d-pad to jump/crouch and simultaneously using the very same d-pad to move left/right is awkward, the way you have to position the thumb to access two buttons at the same time, but for most of the time I test SpelunkyPSP on desktop while developing so my experience with PSP controls may be off
• Taking the golden idol didn't trigger the boulder trap - Not implemented yet
• Music doesn't loop - doesn't loop in the original game either, I was thinking whether this is intentional or not at the time of adding music (the theme doesn't loop in a seamless way), still don't know, but probably should loop it anyway as you pointed it out

Will leave the issue open until I post a PR with corresponding fixups.
