* Made the debugger command "team_images" a bit more useful: it now accepts a 

team ID argument, instead of only being able to dump the images of the current
  team.
* The debugger commands are now now also built-in without the DEBUG flag set
  (for now).
* _get_next_image_info() now also supports the B_SYSTEM_TEAM constant.
* Minor cleanup.
