No coverage generated if project name contains the word 'template'

[jagthedrummer]

If the project name contains the word 'template' ember-cli-blanket ignores every file in the project, and thus doesn't generate any coverage data at all.

It looks like this is due to the default antifilter and would also affect projects that happened to have the word 'tests' in the name.

It would be helpful to point this out somewhere very prominently in the docs.

@jschilli @sglanzer Is there a reason to not use

antifilter: '//.*(tests|\.hbs$).*/',
instead?
