Register a protocol handler for otpauth:// url's

[robinvanpoppel]

As suggested in #110

This got me thinking, if we were to store information in this format, could we also theoretically interpret it and register as a protocol handler in Windows to save new OTPs 'magically' without setup? :)

Indeed, basically you only need to add a new key in HKCR with "URL protocol" value. However I don't know how to attach it to a specific entry in KeePass. Reading the QR is a good option too, like "Setup by reading QR".

This is possible to implement.
(more information for the implementation: see KeePass - Feature Request 1870)

• We should then Register a protocol handler (in windows). Can the same be done for mono?)
• How does the user connect these settings to an entry?
• Would it pop up a modal dialog?
• What if the user has multiple databases open?
• Does this still work when KeePass is set up to run only one instance.
