Creating project with . in project produces invalid classnames.

[jeff-french]

When creating a ShoelaceMVC project with a Project name like "My.Awesome.Webapp" the class name generated for the code first membership context is invalid: "My.Awesome.WebappContext". Probably need to create a custom template paramter like $safeclassname$ that strips the "."'s out of the $safeprojectname$ parameter. Not sure how to do this though. :/
