many things in one

Changes:

n.b.: I'm viewing on an 11inch laptop screen....if looks totally crap on large screen, disregard, since I expect most Rackers are using a full screen.

- Left justified schedule text because easier for me to read than center justified. 
- Made all schedule text be wrapped in <p> tags for consistency
- Decreased top and bottom padding of schedule text because some text was below the fold
- Moved "We need speakers" to above images so that no one gets the wrong idea for even 2 seconds. 
- Also made speaker circles not wrap, because that pushed everything else below the fold, and our test subject didn't think to scroll (test subject suggested providing talk suggestions on mouse over of speaker circles or something)
- Made "tech talk programs" into a link
- Increased proposal description from a single line to a textarea, with a placeholder asking for detailed description and bullet points. Getting this information will really help the selection committee even though submitters have to work harder up front.
