"ImportError: No module named CommonMark" with commonmark 0.8.0

Hi!

In commonmark 0.8.0 the module name has been changed from CommonMark to commonmark (readthedocs/commonmark.py#131), which is a breaking change. I've filed readthedocs/commonmark.py#137 upstream about this, however even if they re-release an 0.8.x with the change reverted, and than make the breaking in 1.0 instead, recommonmark will still need to either:

• adjust the setup.py version range from commonmark>=0.7.3 to commonmark>=0.7.3,<1
• adjust the import name used, here:
