removed confusing css formatting and added reload to add function

Removed the underlining from the page titles so users don't think they
are links.  Also, forced the page to reload the additem.html page
whenever a user submits a new party member (resets the input fields).
tweaked clear and show data functions

Created conditionals in the clear and show data functions to check if
local storage was empty before running.  Also changed the text of the
additem link that is displayed.
