Minor web services and forms authentication improvements:
Added forms authentication GUI for developers.
Error handling improvements.
Common.MyClaim brought back to CommonConcepts.
Simplified XmlUtility.Dom initialization (other web services don't need to worry about it now).
Added ProcessUserInfo for Rhetos utilities where web authentication is not applicable.
Modified CreateIISExpressSite utility to allow forms authentication.
Fixed Rhetos project dependencies (Rhetos.Web).
Improved error handling.
Readme file included in Rhetos packages.
AspNetFormsAuth package initializes SimpleMembershipProvider's database table on deployment.
This is a performance improvement to avoid executing the SimpleMembershipProvider's initialization SQL queries on every web request.
The initialization is placed in a separate application (which is called from DeployPackages), because the SimpleMembershipProvider functions require some configuration data in app.config file.
The changes in app.config cannot be added as a plugin for DeployPackages.exe.
Bugfix: Remove superfluous project reference.
Core tool should not reference a plugin repository.
