added class tests for views and wildcard view composers

[josephmancuso]

We may now specify wildcard view composers so if you want a composer accessible in the resources/templates/mail template namespace, before we have to do this:

Viewclass.composer(['mail/welcome', 'mail/goodbye'], {dict here})

Now we can specify wildcard templates:

Viewclass.composer(['mail*'], {dict here})
