- Block and theme improvements. Patch by Ax.
+ block_list() (in block.module): returns an array of block objects for $region. + theme_blocks() (in theme.inc): uses block_list() and theme("block") to actually render them. Advantages: + Decouples blocks content and layout, allows block_list() to be used for non-output purposes (think "pull"). + Unifies naming in theme.inc: render_blocks()) didn't really fit there. + Puts block_list() in blocks.module where it logically belongs. - Removed some cruft from the Xtemplate theme.
