bitbake-user-manual/bitbake-user-manual-intro.xml: Fixed link

I inadvertantly used a &YOCTO_* variable in the book to get
a link to the landing YP page.  Of course this does not work.
I replaced it with the actual URL.  Unfortunately, a previous
commit slipped through that would have prevented the manual
from "making" correctly.

world-image: add extra target

* similar to world target, but collects all PACKAGES
* recipes marked with EXCLUDE_FROM_WORLD are excluded from world as well
  as world-image
* recipes marked with EXCLUDE_FROM_WORLD_IMAGE are excluded completely
  from world-image, sometimes you can build 2 recipes in same sysroot,
  but cannot install them in the same image
* PACKAGES listed in EXCLUDE_PACKAGES_FROM_WORLD_IMAGE are also
  excluded. You can remove e.g. ${PN}-dbg, but keep all other PACKAGES.
