Bump hacking to 0.9.x series

In order to keep this patch to just a requirements bump, ignore new and
stricter hacking rules that are being triggered. Fixing up the code and
turning these on is out of scope of this patch and is for future patches.

Expand © and remove unnecessary encoding lines

The word "Copyright" alone is sufficient to claim copyright, the ©
symbol need not be present.[1] This allows us to expand the "©" symbol
into "(c)" to avoid introducing non-ASCII characters.

As per PEP 263, a Python file with non-ASCII characters must have a
line with "coding: <some-encoding>". Python files containing only
7-bit ASCII characters need no such line.[2]

This commit expands the non-ASCII Unicode copyright symbols and
removes the now unnecessary encoding lines.
