Add comments to Wiki pages

Created by: seeingidog

Implements comments for wiki pages as mentioned in issue #845 (closed). Two questions:

1. The comments reference a Wiki object which changes with each edit. Should they point at the project's last Wiki object?
2. Are the email notifications I added unnecessary?

Let me know if there is anything else. Thanks.

1. yes, last wiki object
2. It notifies wiki author?

1. I've had to use this method to show comments for all revisions of a wiki. Works well.
2. Are you asking this to be changed to notify the wiki author only? It currently notifies the team.
