Boolean PMC without Integer

[Paul C. Anagnostopoulos]

This ticket represents work being doing on a new Boolean PMC that does not inherit from Integer. The work is being done in the sleeker_boolean branch. The central idea, suggested by chromatic, is to eliminate the dependency on Integer and store the boolean value in a PObj flag.

I have implemented a new PMC that passes the boolean tests. It looks like boolean operations are about 20% faster, primarily due to the fact that they don't require allocating attribute blocks.

The sleeker_boolean branch has been merged. This new Boolean appears to be about 20% faster on a boolean-intensive benchmark, primarily due to the fact that it doesn't allocate an attribute block. Thanks to chromatic for pointing out that we could use a PObj flag for the boolean, and thanks to kid51 for helping me merge the branch.
