[m-rev.] Website, For review: Update the coding standard on the website.

[Paul Bone]

For review by Julien.  This is something I implicitly suggested and Julien
also seems to agree with.  Any other comments are welcome.  Thanks.

Website change:
Update the coding standard on the website.

Update the coding standard to say that we no-longer need to module qualify
the declarations, definitions and uses of predicates and functions
throughout the standard library, except where this is used for
disambiguation.

development/developers/coding_standards.html:
    As above.
