Fixes in relation to template.abstract:#4
Fixes phpDocumentor/phpDocumentor2#412

Quick-fix to add the missing search.gif on the correct location.
The template needs to be revised and refactored to be fully
operational; at that point can the definitive location be
checked out.
Fix phpDocumentor/phpDocumentor#413

The search bar and collapse/epand button is broken due to an
error with the jQuery selectors.
By fixing these selectors to get the appropriate elements do
these work again.
