This allows you to register in the web frontend now, and the login server now
checks this before giving a session ID. Note that this is wildly insecure (it
stores the passwords in plaintext!) and is duly noted in the USAGE.
It's a hack and only really works going from New -> Old Gridania, but this does
work! It also means Kawari now actually requires a valid game installation,
since it has to read layer group information.
This is a slightly modified version of the one in Physis, with the required
modifications inspired from WorkingRobot's TemporalStatis fork. Thanks so much!
I ended up just stealing this from iolite, which in turn took it from Sapphire.
I tried for a few hours to get a Rust Blowfish implementation going, but the one
from Physis didn't work. I'll try again later.
