UI Adjustments

A couple adjustments to the interface:

 * Making Projects Index and Show a consistent width
 * Stubbed out stats box, but didn't complete -- that will get its own feature branch
 * Fixed sizing of ui elements when listing tasks
 * Removed duplicate information from listing tasks (owner and reporter prefixes)
 * Expanded seed data for `Rails.env.development?` to test UI easier
 * Making task ordering consistent
