Revamped the unlock system. Currently it supports the following methods:

DP - dance points, what Miryokuteki had in place
AP - arcade points, like MAX2 arcade
SP - song points, like MAX2 home (though I don't know the exact system)
CS - clear stages, like 5th home

Somewhat strewn but not supported yet:
!! - Toastys seen
EC - cleared extra stages
EF - fail extra stage (don't quote me on these two yet, I haven't tried them yet)
RO - roulette (theres fifteen roulette slots, but its not implemented yet)

Also updated the INI to store values for these means of unlocking.  The system
still isn't "optimized" yet, though.
