Removed double label on boolean inputs, and changed to input-mini/input-small on date/time selects

Boolean:
This was adding the label twice, once as a normal label on the left and again as a checkbox wrapped with the label. I've commented out the first label since this seems un-necessary.

Timeish:
I found date and time selects were ending up on separate lines because of the way the fluid boostrap css converts span1 and span2 to block elements. Switching to input-mini (and input-small for month) fixed this. There was also a placeholder named after the class being added to the selects which is un-necessary. I commented this out.
