[FIX] CSS: When using Chosen, dropdown menus at the bottom of "panels" (e.g. tracker field options) would be cut off making the menu unusable. This fix makes ugly scrollbars appear when you select the menu, but at least functionality is restored. CSS file changed manually as i still can't compile LESS

[FIX] CSS: Improvement on previous commit, ugly scrollbars are only needed in panel-collapse (accordion) panels, "overflow: visible" works just fine on normal ones like modules
