autotype tokens are case sensitive

[RichardKraus]

The documentation references the keepass website in which it states "KeePass 2.x Only: Special key codes are case-insensitive".
As you state you support "KeePass 2.x style" autotype sequences it would make sense to also handle the tokens the same way.
Currently tokens like {Password} or {UserName} generate an error.

Reasonable request! I'll take a look at it when I can.
