 Read-101's search support is broken in pretty much every format.

 With text files I see the following when the forward search button is
 pressed:
 {{{
 Traceback (most recent call last):
   File "/home/olpc/Activities/Read.activity/readtoolbar.py", line 141, in
 _find_next_cb
     self._search_find_first()
   File "/home/olpc/Activities/Read.activity/readtoolbar.py", line 91, in
 _search_find_first
     self._view.setup_find_job(text, self._find_updated_cb)
   File "/home/olpc/Activities/Read.activity/textadapter.py", line 321, in
 setup_find_job
     text=text, case_sensitive=False)
   File "/home/olpc/Activities/Read.activity/textadapter.py", line 401, in
 __init__
     Gtk.gdk.threads_init()
   File "/usr/lib/python2.7/site-packages/gi/module.py", line 243, in
 __getattr__
     return getattr(self._introspection_module, name)
   File "/usr/lib/python2.7/site-packages/gi/module.py", line 105, in
 __getattr__
     self.__name__, name))
 AttributeError: 'gi.repository.Gtk' object has no attribute 'gdk'
 }}}

 With EPUB files I do not see anything logged, but nothing gets searched
 for either (or potentially previous searches are used).

 With PDF files I see:
 {{{
 Traceback (most recent call last):
   File "/home/olpc/Activities/Read.activity/readtoolbar.py", line 131, in
 _find_updated_cb
     self._view.find_changed(job, page)
   File "/home/olpc/Activities/Read.activity/evinceadapter.py", line 318,
 in find_changed
     self._view.find_changed(job, page)
 AttributeError: 'View' object has no attribute 'find_changed'
 }}}

 Ideally we should start searching for text when the forward/back buttons
 are pressed, starting from the last match of an item (if previously
 entered) or relative to the current shown location.

 Tested on 12.1.0 os21.
