Improved Selector's handling of the folder icon

Browse Source 
Renamed fontHeight to lineHeight, since it is computed using both the
font's line spacing and the height of the folder icon. For the latter,
use the actual icon height plus two pixels spacing instead of the
hardcoded value of 20 (16 height + 4 pixels spacing).

Fixed recently introduced bug where "top" is added to the folder icon
y-coordinate twice. Also center the icon vertically when a large font
is used.

Don't crash if the folder icon is missing. This could only happen on
broken installations though. Also don't search for the icon twice:
SurfaceCollection::skinRes already calls addSkinRes internally when
there is no cached surface for the key.
