Make a new-pun page and submit handler

Also add a redirect wrapper in ViewLib because it makes
me feel fancy.

Create a table-listing of the current puns in the database for
easy viewing. Setup the beginnings of a pun edit page, much like
the user edit page.

Also create a form handler for the pun adding thing. Just to make
sure that the puns are at least 10 characters long, ya know?
