grok.template doesn't complain if the given template does not exist

[Christian Theune]

I made the following mistake (appending .pt to the template name but asdf.pt exists):

class Foo(grok.View):
    grok.template('asdf.pt')

and received the following error message:

zope.configuration.config.ConfigurationExecutionError: martian.error.GrokError: View <class 'rdbexample.app.DepartmentList'> has no associated template or 'render' method.

This should say that template 'asdf' doesn't exist.

The latest grokcore.view splitted View into View and CodeView. View always needs a template, so the error message is already much clearer as it doesn't need to take a render() into account.

Instead of "no associated template or render method" you only get "has no associated template". (With the freshly released grokcore.view that's going to be in 1.0beta1).

It can be made more clear if grokcore/view/templatereg.py is modified to keep track whether there's a grok.template setting and to return that in the error message when applicable.

So: partially fixed, but needs a bit of improvement.

I was the last one to touch it (together with christian klinger), so I can take a stab at it.

I will pick up this bug again when the new template-registry stuff is merged...
