[Buildroot] [PATCH 1 of 2 for-2014.05] website: rework Contribute page to avoid duplication with manual

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

The manual contains details about how users can contribute to
buildroot. The website also had such a list, but with much less detail and
not containing all topics.
In order to avoid duplicating this information, simply list the different
topics without detail on the website, and add a link to the relevent
chapter of the manual.

Note: the current manual does not have the updated info. At this instant the
info is still on the git version of the manual:
http://nightly.buildroot.org/manual.html#_contributing_to_buildroot
When the 2014.05 release is made, the manual will be updated and all will be
well.
