Subject: [PATCH] Subgallery navigation, other misc stuff:

Add initial subgallery navigation, layout tweaks, start experimenting
with a custom jquerymobile data-theme ('h' for horde) basically just
to get a dark background for the thumbnails while maintaining the rest
of the horde-wide usage of data-theme 'a'.
