Add support for directed identity in OpenID 2.0

[martin@…]

There could be a config option for the openid plugin, where one could configure the OpenID provider to use. This might be useful in scenarios where a known (company wide) OpenID provider should be used for many projects or if the user would like to provide 'one click' usability for login.

Something like

[authopenid]
default_identifier = https://openid.ee

and the link 'Log in with OpenID' would automatically start the flow that is similar to currently entering openid.ee to the identifier box and clicking 'log in'

My own interest of course is to use openid.ee with this feature, so a patch might come soon :)

Here's a quick patch to do exactly this:

to configure, use

[trac]
default_openid = https://openid.ee

clicking the "OpenID Login" in the navbar initiates a directed identity login with ​https://openid.ee Tested and works as expected.
