ENH: multiple enhancements

* fixed layout that was broken due to mis-placed div closing
* updated style for search results
* fixed highlighting (was not working due to case sensitivity, now
 is done with http://bartaz.github.io/sandbox.js/jquery.highlight.html)
* added scrolling to the paragraph with the searched for word. Hacks had
 to be added due to id's not located directly in the sections containing
 the searched paragraphs! Scrolling is not always working precisely, not
 not sure about the reason (try "group" search results)

TODO:
* make indexing more intelligent
* look into indexing errors
* play with it on more components of the standard
* handle <a> in #dicomText so that the destination URL is loaded in
 the same div
* improve presentation, add QIICR logo
* dicom.css referenced from the standard text is not found
