So "bjam pdfinstall" will now build and install the PDF to the current directory.
This works around some problems that the previous versions had if the user did not have an FO processor installed (basically Daniel James was unable to build the HTML docs for the distribution if the pdfinstall rule was implicit).
[SVN r79492]
Mostly to use the images and css files under doc/src instead of
doc/html, usually be deleting the settings in order to use the defaults.
Also add 'boost.root' to some builds in order to fix links which rely on
it.
[SVN r63146]
replace links within the boost distribution with links to the the boost site,
which is useful for generating pdfs and standalone documentation.
Implemented with John Maddock. Fixes#1166.
[SVN r51261]
Tweaked some existing Jamfiles so that PDF build finds all the necessary image files etc.
Tweaked fo.xsl to provide more options by default, and improve formatting.
