Test case included

This was partly implemented in 1.0.0, you can now set an individual tag's metadata. In future almost the same functionality as in this PR would be implemented as #66, in a way the tag's metadata could be changed using all the settings setters and the new +bemto_scope as well.

Right now, in 1.0.0, if setting the individual tag's metadata won't be enough for you, you could patch the bemto_tag_metadata object manually, like this:

- bemto_tag_metadata.a.content_type = 'block'

+b('a').link
  +e.element
  +e('a').element

Warning! this, though, undocumented feature and could be changed in future minor versions when the #66 would be implemented.
