Store only relative path in theme_mod() for 'header_image' and 'background_image'

[mikeschinkel]

In /wp-includes/theme.php it stores full paths for 'header_image' and 'background_image' in the theme mods in wp_options. Is there a reason why these can't be set to relative paths? Storing absolutely paths results in yet another path to have to fixup on deploy.

I think the full path is necessary beause of the pretty permalink option. Imagine you are on same month archive and the link must work directly read out from options w/o any additional calculation. It's somewhat a concept in Wordpress to use absolute URLs instead of relative ones, so it's a constraint in using the software.

For deploy, you need to go through all (serialized) option values and replace the old URL with the new one. It's a PITA, yeah, there are some tools that deal with that.
