Rework the code provided by Kadlcik Libor for loading/showing icons in Openbox menus.

This changes how the imagecache works, you can load an image into it directly,
or you can load it by name (then it will load it from a file on disk).

NOTE: The name part is incomplete, as it needs to use the freedesktop.org icon
spec to search for the right file.  Also to resize it should look for another
icon on disk with the same name but different size (icon themes).

-    All loaded images are cached. There's no separate cache for the images,
-    instead they are simply stored in image cache (RrImageCache) as RrImages,
-    ready to be used.
-    Every RrImage loaded from file is associated with name of the file. This is
-    done by file name table (RrImageCache.file_name_table), which is a simple
-    hash table, where file names are keys to pointers to RrImage.
-    If you request to load file that is already in image cache, nothing will be
-    loaded and you just got the RrImage from cache.
-    When RrImage is destroyed (see RrImageDestroyNotify), the file name - pointer
-    to RrImage pair is removed from the file name table.
