[ENH] Modules: Add parameter action to module Last Changes (last_modif_pages)

https://avan.tech/item68084

Added a new parameter to the Latest Changes module (last_modif_pages), the 'action' parameter. It allows to show action performed on the pages recently.

I also translated some parameters to french.

Examples of usage:

1. {module module="last_modif_pages" action="y" max=5}

2. {module module="last_modif_pages" date="y" user="y" action="y" comment="y" max=5}
