Image file url is not external.
XPath to parse ENCODED_OCR selects parent span.
No longer apply arbitrary positioning.
Proper highlighting and pages sizes.

Pages are different sizes, and its impractical to fetch the width/height of each
page in the preprocessing function for the viewer. So do it on a page by page
basis in javascript caching the results. Previously it was assumed that all the
pages were the same size as the first page in the book.
Attempt to get the page dimensions from FITS before checking Djatoka.

Also some clean up and restructuring.
Add support for tesseract 3.2 requirement in book pack.
Fix for parameter change.
Removing unused files.
Scroll overflowing text in the full text modal dialog box.
mend
Get all terms not just terms in spans.
Play nice with the overlay in FF.
Fix for change to islandora permissions handling.
jQuery.param rather than string concatination.
Multilanguage support for search highlighting

Use PHP's mb_strtolower rather than XPath's translate to enable greater
support for languages other than english. Also clean up the url generation
for solr.
