Hightlight rows on tables when mouse over in admin UI

[#1]

When hovering over a row in a table that line should highlight so it makes it easy for users to see the whole row of data. This currently works well in the report interface but is not available on all admin UI elements such as dashboard manager, user administration etc

See the table example on this link :-
