Changes

External links in web view go to Safari; (possibly) pdf articles can be
opened in another application (need to check on a real device); XML
location was changed (which we need to figure out the issues with
this); AND some work has been done toward trying to figure out the
multiple keyword search
White "blank" screen on init

Got it to be a white blank screen instead of the gray. In addition,
there were some issues when going to the more section and then back
that you had to select a different trial if you wanted to click on the
same one that you were viewing before. It still is highlighted, which
is another problem, but you can now reselect it to see it instead of
having select another first.
