[web] Slight tweak on jQueryUI's colors on links (related to #4564046)
Follow up to commit 16f550b48d57 which was somewhat brutal. This change
only overrides jQueryUI's CSS rules inside tab panes and leaves actual
tab buttons alone.
Schema of the data
------------------
First take a look at the data schema_ then try to remember that you are browsing
through a heap of data by applying stylesheets to the results of queries. This
site is not a content management system with items placed in folders. It is an
interface to a database which applies a view to retreived data.
