K-9 Mail now opens the Accounts Activity when started with an Intent

with an enclosed URI with a content type of application/x-k9settings.
This allows a user to bootstrap K-9 Mail configuration by email a
settings file from one device to another, perhaps using a GMail
account on the receiving end.
