New component and reporting pages on Core Trac

[nacin]

[322:332] added Trac component pages and also a new reporting page. I'll be using this ticket for further tweaks. If any designers or developers want to weigh in and improve things, feel free to comment here.

Some minor tweaks:

When you're scrolling through the list of collapsed components, sometimes it's hard to quickly tell which description goes with each heading. Adding a little bit more margin to the top of each heading helps separate each section so it's easier to scan:

.compact-components .component-info h3 {
margin: 15px 0 10px;
}

The page also needs some space between the component list and the footer, since right now the two almost collide. 30px of space should even it out with the other .org pages. I was having trouble figuring out which div would be best to add it to, though, since it should only be for this page (since other pages account for the spacing in other ways).
