8768ff07b6 Fix AhoiPolloi, be a bit smarter about encoding. 
HTML character encoding in the context of HTTP is quite tricky to get
right and honestly, I'm not sure if I did get it right this time. But I
think, the current behaviour matches best what web browsers try to do:

1. Let Requests figure out the content from the HTTP header. This
   overrides everything else. We need to "trick" LXML to accept our
   decision if the document contains an XML declaration which might
   disagree with the HTTP header.
2. If the HTTP headers don't specify any encoding, let LXML guess the
   encoding and be done with it.

6727e9b559 Use vendored urllib3. 
As long as requests ships with urllib3, we can't fall back to the
"system" urllib3, since that breaks class-identity checks.

68d4dd463a Revert robots.txt handling. 
This brings us back to only honouring robots.txt on page downloads, not
on image downloads.

Rationale: Dosage is not a "robot" in the classical sense. It's not
designed to spider huge amounts of web sites in search for some content
to index, it's only intended to help users keep a personal archive of
comics he is interested in. We try very hard to never download any image
twice. This fixes #24.

(Precedent for this rationale: Google Feedfetcher:

7c15ea50d8 Also check robots.txt on image downloads. 
We DO want to honour if images are blocked by robots.txt

5affd8af68 More relaxed robots.txt handling. 
This is in line with how Perl's LWP::RobotUA and Google handles server
errors when fetching robots.txt: Just assume access is allowed.

3235b8b312 Pass unicode strings to lxml. 
This reverts commit fcde86e9c0 & some
more. This lets python-requests do all the encoding stuff and leaves
LXML with (hopefully) clean unicode HTML to parse.
