Expand the section on creating/managing a project website

Link to original bug (#508465)

Description

We should include some discussion of the URL, the relationship between the Git repository and the website (e.g. how frequently one is pushed to the other), services provided, etc.

Random thoughts:

• The default implementation redirects to the project's PMI page.
• You need to be a committer to edit website content.
• Consider asking the webmaster to add your website Git repository to Gerrit.
• Contributions to the website can be considered as part of the merit for becoming a committer (it's really up to the project team).
