Title: Added sorting to conversations

In preparation of implementing stickying, I've added a updated_at default scope to the conversations.

This does a few things
1. Conversations now have timestamps
2. Conversations are ordered by updated_at
3. Comments `touch` conversations
4. Timecop is now in the test group
