[Enhancement] Make it simple to change my password

[leogott]

Please improve the workflow for changing a password with a website, and make it possible to do so from within the browser.

Usually to change a password with a service one needs to enter the old password and the new password twice. Currently this is not possible with gopassbridge alone.

It would be great to auto detect update password field and to pop up a update password validation button, the way Firefox Sync does it would be perfect.

This would require changes in the gopass jsonapi as first. I'm happy to assign the issue to someone who wants to build a PoC as a first step.
