[x] Exceeding character limit breaks paper layout

[amberreeves]

Going over text limit in all sections where user inputs text causes the formatting of the newspaper to not be displayed correctly.

We now truncate the headline, byline, and article text. You actually cannot go over the text limit, it validates the letter count, but if you enter a single word like "aaaaaaaaaaaaaaaaaaa..." it breaks the preview.
