Drop official support for Python 3.2

We should still be able to run on 3.2, but current versions of pip made
breaking changes to stop supporting 3.2.  There are several things we
can change (one noted here, but also we can use `u''` strings rather
than `six.u()`.

Honestly, I don't know how many people run old versions of Python 3,
especially as far back as 3.2, we could probably safely drop 3.3, and
thus not need to support trollius on Python 3.

 First, you need to install all of Qtile's dependencies (although some are
 optional/not needed depending on your Python version, as noted below).
 
+Note that Python 3 versions 3.3 and newer are currently supported and tested.
+Python 3.2 should still work with Qtile, however the latest versions of pip
+have dropped support for Qtile, so you will need to either use an older
+version, or install all the required packages by running the respective
