Initial import of v.1.1.2 of markus_petrux's Akismet module. This version is the working 4.7 version. 5.0 port coming shortly.

Approved comments are now checked against akismet server, automatically unpublished if flagged as spam.
There are some implementation details that are actually pending on several issues found in the comment.module. Please, read @TODO notes in source code.

For now, when akismet tell us a comment is spam, we unpublish the comment and prefix the subject with [SPAM].
There is more work, yet, to do. see @TODO notes.

Warning: It is finished, yet.
