Consider switching from chardet to charade

I think chardet has not been maintained for a while now and it's not easy to choose between the several forks.
[Charade][1] has some improvements and should work out of the box.

Pros:
- works with python >= 2.6 and python 3
- drop-in replacement

Cons:
- feedparser needs to be updated as well (but RSS plugin is broken with it currently anyway)

It would also be also possible to do something like "import charade as chardet" and then on exception import chardet to ease the switch.

(On a sidenote: I am new to github, hope i have everything done well...)
