 Themes
 ------
-Theme support is very rudimentary, basically you create functions for each of the parts of the template, and put them in a file named the same as the theme. The functions that you need to declare are as follows:
-	bpgallery_ThemeName_head()
-		what's it for?:
-			This sets up the header for the page, generally
-			everything until the first picture. So, the title bar
-			and any menus you would like to use
-		available variables:
-			$TITLE       - the title for the index page
-	bpgallery_ThemeName_tail()
-		what's it for?:
-			Closes the page, is the last thing to be printed.
-		available variables:
-			None
-	bpgallery_ThemeName_description()
-		what's it for?:
-			if there's a description set up (i.e. a description.txt
-			file) then this is what it'll be wrapped in. It comes
-			just after the _head.
-		available variables:
-			$DESCRIPTION - the content of description.txt
-	bpgallery_ThemeName_stylesheet()
-		what's if for?:
-			It generates the stylesheet for the page.
-		available variables:
-			$WIDTH       - the width of the images
-			$MAXHEIGHT   - the maximum height of the image
-	bpgallery_ThemeName_thumbsline()
-		what's it for?:

-		available variables:
-			$filename    - the name of the file
