autopep8 is not the default

The version in debian is painfully slow (even with parallel, I ran it for 5 CPU
minutes and it still didn't finish). If people want a formatted debug version
they can build one, but I'm not going to sit and wait for it :)
Add licensing clarification

Based on [1], noting "MIT" as the type of licence is ambiguous. In fact the
test of this license is the OSI approved Expat version of the MIT license, so
reflect that in the comment at the top.
