Recording Tasks

- Log Task works! Server-side verification (see /post/timeline)
- Timeline is now user-based (e.g. /m/1 for Serr)
- Root directs to recent.phtml; for now, all users and timelines
- TODO: client-side verification; notification on submit; accept more
date formats; code needs clean-up
- TODO: profile-view, esp. when viewing other users or when not logged
