Moved Burndown link to the left set of links so that numbers are over on the right by themselves. Vertically-centered the estimate/time-spent number totals in the bar up top.
A great deal of groundwork for the Scrum for Trello settings. The settings aren't finished yet, so the icon itself is still hidden (commented out near line 188). Will attempt to finish the settings very soon. This commit includes icons that will be used by the settings link and the small window/frame it pops up.
