Notes

• Fixes #2 by introducing a response count limit and character limit.
• Reformatted bot.py according to PEP8 and resorted imports, removing unused statements.

Testing

• Added two unit tests, one for checking that too-large replies are rejected, and one for validating the combined_responses are truncated.
• Attempted running of unit tests per the README but received an error:

  
  (env) C:\Users\clyde\prjx\xkcdbot>python -m unittest

FAILED (errors=1)

This failure occurred on `master` before I introduced any changes. Commenting out `test_database.py` shows tests passing:

(env) C:\Users\clyde\prjx\xkcdbot>python -m unittest discover ....Comment size 10001 exceeded 10000 response char limit, saving and skipping. ..
