Fixes a bug where the wrong account could be marked as "in use" when the
game is launched if there are multiple accounts that share the same
profile ID. This can lead to the launcher trying to refresh an account
that's currently in use by the game, leading to "Invalid session" errors
in-game.

This makes the account system much more modular
and makes it treat errors as something recoverable,
unless they come directly from the MSA refresh token
becoming invalid.
- We now use the new endpoint for loggiong in via XBox tokens (/launcher/login)
- We now check game entitlements instead of only relying on MC profile presence
- Accounts can now be added even when they do not have a profile
- The launcher will guide you through selecting a Minecraft name if you don't have one yet
