Remove KeePass integration (dashpay#4628)

* Remove KeePass integration

This integration is not actively supported. It has zero tests, little documentation, and has not really been actively maintained. As far as I can tell, noone uses this integration, and even if they do, they will simply have to copy/paste password from keepass instead of using this integration.
