Subject: Fix for non-matching entities (#161)

* Add test to illustrate issue

* Provide some test fixes

* Don't neglect CounterClockwiseContourIntegral

* Fix ~10% of cases not matching

strncmp returns 0 if the first 'len' bytes of cmark_entities[i].entity
match s; we check equal length in the first if by checking if
cmark_entities[i].entity[len] == 0, but we neglect the case where cmp ==
0 && cmark_entities[i].entity[len] != 0.  This should be treated as the
same as cmp < 0, because strcmp("abc", "abcd") < 0.

* Don't depend on py3.3 in tests
