Update dependency declarations in Debian package and requirements.txt

- Loosen dependency on dogpile.cache to >= 0.5.0, as no new features
  from 0.5.1 are actually used.
- Loosen dependency on requests to >= 2.0.0, as no new features from
  2.0.1 are actually used.
- Drop html5lib dependency, as it isn't actually used.
- Loosen dependency on beautifulsoup4 to >= 4.2.0, as there are probably
  no new features from newer versions used.

All loosened dependencies are done because older versions aren't
available in Debian yet.
