List view generation changed

*View generation code and hierachy simplified a bit.
*Got rid of the SqueezerIconicItemView, which has become unecessary since we now
 have the image cache.
*Introduced a new pending artwork icon.
*Added some more javadoc to the base classes in the Squeezer framework.
*Decreased the left padding in lists, to avoid inadvertently playing a song,
 when trying to hit the context menu.
*Slightly increased the size of the group views in the search result, to make it
 easier to use them.
Format the ternary condition consistently.
