[ENH] Modules : Add new parameters to Latest Changes module (last_modif_pages)

Added four new parameters to allow displaying more information about the last modified pages in a wiki page.

• Date : shows the dates when the pages were edited
• User: shows who edited the pages
• Comment: shows descriptions of the changes made to the pages.
• Maximum comment length: maximum number of characters in comments allowed before being truncated.

With this code: {module module="last_modif_pages" notitle="n" title="Les pages récemment modifiées" nobox="n" date="y" user="y" show_namespace="y" comment="y" max="5" maxcomment="20" }

{module module="last_modif_pages" notitle="n" title="Les pages récemment modifiées" nobox="y" date="y" user="y" show_namespace="y" comment="y" max="5" maxcomment="20" }
