Fixes #18

Thanks a lot. Will review this, and publish a new build, as soon as I can.

Looking at test output in travis.ci, there are a lot of invalid escape sequences in regular expressions:

test/test_collect.py:31
  /home/travis/build/ropez/pytest-describe/test/test_collect.py:31: DeprecationWarning: invalid escape sequence \s
    "\s*<DescribeBlock (')?describe_something(')?>",

These needs to be fixed, probably by using "raw" string literals, i.e change "\s*..." to r"\s*...".

Example output: https://travis-ci.org/ropez/pytest-describe/jobs/487850038

I'll take care of the regexps

Thank you! Sorry for a late reply, was going to fix it now, but you were faster :)

It's now published as version 0.12.0. Thank you @kondratyev-nv
