Momen2m 1.34.0

Share the welcome page from the app

1.33.0 added bienvenue.html, a French welcome page for someone who has never heard of
Momen2m. This release puts it one tap away from inside the app.

New button in Progress → Share: "Partager la page de bienvenue" (shown when the app
language is French). It opens the system share sheet with a short ready-made message and the
page's address:

Bonjour ! Voici Momen2m, une petite application gratuite qui aide à garder le fil des choses
simples de la journée, en douceur. Tout est expliqué sur cette page :
https://purgator.github.io/Momen2m/bienvenue.html

Where the share sheet is not available, the text is copied to the clipboard instead, with a
toast saying which happened.
