Reviewed by Tim Horton.

Provides the initial support for the find in PDF functionality. This
is done by querying the PDFDocument for the string that was passed in
for search.

In order to accomplish this we need to keep track of the last string
that was searched for. If the target string is the same as the last one
then we need to continue the search from the last match/result we found.
We keep track of the results as the current selection. If the target is
not as the last string we found, then we need to clear the selection
before we attempt to search for the string.

When we find the string we will update its selection to the one that
was returned to us from PDFDocument and potentially scroll to it if it
is currently out of view.
