Few Small Fixes From macdguy's Last PR

Fixed: Display errors with the overlay on fanart and screenshot
nivosliders (tab_game.php)
Fixed: Nivoslider and Flip JS libraries were not being loaded on the
game edit page (broken artwork)
Fixed: Reported Games in Admin CP - Scrolling Description div had a
fixed width that would sometime cause the containing table to grow
bigger than the page wrapper when multiple games exist in the table.
Additional: Incremented version parameters on CSS includes to force a
browser re-fetch of those files.
