[documentation] module pages linking to handbook pages

[Charlie Lowe]

Someone has just made the suggestion that project module pages should 
link to handbook pages:

http://drupal.org/node/44233#comment-82569

I think could be a big plus because


1) The individual project pages are often the first place someone goes 
for looking at module when thinking of using it. Good place to link 
directly to help. Seems an obvious place.

2) The Drupal modules and features pages often provide additional 
information about a module which could help people in choosing what 
module to download or pointing them to additional help when they have a 
problem.

3) Providing a link from the individual project module pages could 
create incentive for contrib module developers to assist in keeping the 
docs updated and to provide additional docs.

Additionally, it seems like it would only help to have all the theme 
projects link to the general theme help sections. Translations, too.
