Improve signup page form layout

[devilesk]

The signup input description notes are too small. They should also be moved from after the input to before the input under the header.

For example "Please be sure to mention other leagues/divisions you'll be participating in." should be directly under "Statement/Availability:"

"1 being least comfortable 5 being most comfortable" should be bigger and under "Comfort/preference"

Also for the role preference section, add the labels "least" and "most" next to each end of the 1-5 radio button groups.
