Add better support for Api keys

[dnewsholme]

Passwordstate splits api keys into multipe types currently the module only supports use of system wide and password generator however system wide doesn't seem to function for all things such as moving passwords.

The following should be all supported which requires a mechanism to automatically select the correct key when hitting the url.
