Switch auth hashing algorithm to bcrypt

Currently in the process of migrating over to Laravel because Adonis is not what I thought it was.

Unfortunately Laravel doesn't support scrypt hashing for authentication, so I wrote a rotator into the existing codebase that will rehash your password and store it as bcrypt on login.

I had invalidated all old sessions and now you must re-authenticate to rotate your hash.

Sorry if this is an inconvenience for you.

Tremendous improvements coming soon!
