Title: Added "Clear Question" feature to exercises, User Info displayed on Contact Us and sidebar spacing fixes.

Clear Question button added to questions. I put it near the "Check Answers" button.

Added user info to Contact Us page so that problems are easier to debug.

Minor sidebar spacing fixes.
