Tweaks to proposal submission fields

Requested by Luke:

*Audience Field*
On the form fields for talk submission, there's a field that I asked for called "audience". I asked for it to be short answer, and I see this is done. Thank you! 

The size of the box is a bit too short of an answer. Can that box be made to span the full line (make it equal in width to "objectives", below?) 

I don't want to get a paragraph, but I want more than one word. :-)

A couple more items, along the same vein: 

* I would like the "title" field width to match my request for the "audience" field width, above.
* The "description" field is far too long, especially since we asked for a 400 character maximum. Can we make it have a height equal to three lines of text? (Right now it's about 8 lines...)
* "Objectives": same as description. Also, can we add a 400 characters notice/restriction, just like "description"? This should be two or three sentences, not an essay.
* Can we make both of the last two fields ("additional notes", "additional requirements") also be three lines high? They don't need to have 400 character restrictions; they just need to be smaller.
