Fix PDF install rule so that it's explicit and automatically invokes a PDF build when specified on the command line.
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 r79500]
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]
Added make_signed, make_unsigned and is_complex.
Added docs for some previously undocumented traits: is_signed, is_unsigned and decay.html
Added synonyms for some traits that have changed name in the latest C++ std draft.
Re-organised docs, moved docs out of the main doc build for now (it takes too long).
This also fixes issues: http://svn.boost.org/trac/boost/ticket/492 and http://svn.boost.org/trac/boost/ticket/1008.
