[patch] Bug 439974: English documentation enhancements

[thomas harding laposte net (Thomas Harding)]

Hello,
I created bug Bug 439974
<http://bugzilla.gnome.org/show_bug.cgi?id=439974>

This patch adds command line, custom shapes and and a little section
about color selector box to the manual.

(Command line and custom shapes chapters are just xml formatting of
existing doc).

Also, it adds hardcopies.makefile which allows to build pdf, postscript
and html versions (requirements in README.hardcopies bug attachment).

I have no capability to add the content of this Makefile to Makefile.am,
so if somone knows automake enough to do that, I'll be glad to him to
do it :)

Notes:
    - the two added figures needs to be replaced by English versions
    - I need a good reviewer for section 3.4.1 I written (I'm not very
      fluent in English)

Regards,
