Created concept of Leading Comments - sort by karma + .5 descendant karma.  Created two ways to view leading comments - all (sorted by time) and subscribed (ditto).
Removed debugging statements.
Removed unnecessary import.
Required user logon to view dashboard page.
Made descendant_karma optional.
Prototype of leading posts in dashboard.
Ensure that things that don't need descendant_karma don't look for it in the db.
Fixed subscribed comment spam filtering.
Updating descendant karma now happens in a single db UPDATE.
Descendant karma calculating script no longer loads all links and comments into memory.
Merge pull request #85 from PotatoDumplings/interesting_comments

Add interestingness metric and pages to view comments/posts sorted by it
