Media Viewer PdfJs - latest pdf.js libs, added new search

[GoogleCodeExporter]

I've updated the PdfJs part of Media Viewers.

The following enhancements is completed
- Latest pdf.js libs
- Added new search
-- New toolbar displayed when search icon clicked
-- Search hit highlighting, highlight all, case sensitive search, move to 
next/previous hit.
- Improvements to lazy load thumbnails
- Made IE10 a requirement. It does work in IE9, but performance is terrible and 
cannot be worked around. This is due to lack of support for typed arrays in 
IE9. Possibly this can be configurable if someone insist on using with IE9.

Things that still need to be done before release
- The iframe version of pdf.js not updated, since PdfJs is almost feature 
complete remove that embedded viewer to save maintenance
- Review new search toolbar, buttons/labels.
- Minor fix for removing search hit highlighting when resizing and closing 
search toolbar.

iframe 'mode' has now been removed. The viewer will now use the embedded viewer 
and will ignore the 'mode' attribute if supplied in the config.

All the todo items in Peter's list have now been done, apart from removing the 
search hit highlighting. I have recorded this separately in the GitHub project, 
so this issue can now be closed.
