Minor edits to election_cast_confirm and _castconfirm_docast for clarity

I moved the ballot tracker below the cast ballot button and made it smaller.  I did this blind and I hope I counted the if's and endif's correctly...could someone check that the smart ballot tracker in election cast confirm shows up in the right spot? 

I reworded the "we have received...you encrypted ballot" statement.

I separated the "I am" from the "cast this ballot" button.
