Search Results Items -- make only the title a link, and remove view button

[lhenze]

#22 from NYU A11y Review.

"The construction of the search results currently encloses the entire record/item in an tag - e.g. - the whole thing is a link. This doesn't allow the individual information to be easily accessed by the screen reader user. In order to provide more context about the result, we recommend making the result title a

and a link."

We've also discussed removing the view button as it's redundant and unnecessary; all of our usability testing participants knew intuitively that clicking the title would lead to the detail page.
