Fixed most of the errors reported back from hacking 0.9.2.
Specifically:
- E128 continuation line under-indented for visual indent
- E251 unexpected spaces around keyword / parameter equals
- E265 block comment should start with '# '
- H305 imports not grouped correctly
- H307 like imports should be grouped together
- H402 one line docstring needs punctuation
- H904 Wrap long lines in parentheses instead of a backslash

But opted to ignore the following for now:
- E122: continuation line missing indentation or outdented
- H405: multi line docstring summary not separated with an empty line

This fixes lp1175367 and lp1175368 by redesigning the memcache crypt
middleware to not do dangerous things. It is forward compatible, but
will invalidate any existing ephemeral encrypted or signed memcache
entries.
