New Logo!

Changelog:

1. Added Microsoft Account Support (!)
2. Changed GUI a bit (changed background and added the 'Accounts' tab)
3. The installer works now!
4. Made it so that the password window WON'T show up when the account type is either Offline or Microsoft.
5. Realized the updater didn't work. So I fixed it. (Testing these things are really hard might even remove this.)

Note: This is a pretty big update. You might wanna download this ig.
