[drupal-docs] Idea - move help text out of code into database

[puregin]

     I'm going to re-float here on both lists the idea of having each
module's help texts provided within the Drupal database, as opposed to
being hardcoded in.

     Advantages: the help text documentation would be
        - easier to maintain
        - easier to translate
        - easy to tailor to user's experience level and preferences
           (tag each helptext with a 'User experience level" vocabulary
            and select the text according to the user's preferences)

     I think it would make the code easier to maintain also.

     Code review and documentation review could occur
independently.

     Comments?
