Bug fixes and logging up to INFO for release

Bug Fixes:
* Tree was stuck showing as loading when user had no feed subscriptions.
* Unread count was incorrect (bad join when DB had > 1 user account).

Changes:
* Allow openid to connect to localhost, but added a transform to remove
this in release
* Added a release transform to increase the logging from debug to info.
Added wcf api

Made the windows service expose a wcf api to allow the web app to
request an rss feed be refreshed. This is particularly important when
adding new feeds as otherwise we don't get the articles until a
background refresh occurs.
