[CLIENT] Loginscreen losing active element on focus loss

Hi Guys, this is a rather minor bug. How to reproduce.

1. Start lolclient
2. Go to login screen, where you can enter your credentials
3. Click on Username field, watch the | character appear and disappear.
4. Switch to another application
5. Switch back to lolclient
6. The previous focused element is now not focused

Is pretty annoying for people with password manager (keepass for example) that require you to enter your masterpassword. My current workaround uses 3 Tabs before entering my data, but this changes from time to time.

I would assume that if there is no username safed i would start to type at the username field and if there is a username safed i would expect to start typing at the password field. Also i would expect to resume where i left off when switching from/to lolclient.

Kind regards, Robert
