v1.7.2 Mbin release

We are excited to announce the release of Mbin v1.7.2! This version is packed with important bug fixes and performance improvements, focused on bug fixes rather than new features.

The main improvements are:

• Fixing many PHP undefined, null or other errors that admins might see in their production logs.
• Resolving several templating null issues.
• Removing CSRF tokens from public forms (when user isn't logged-in), reduce unnecessary large amount of sessions.
• Migrating Symfony sessions from Redis to PostgreSQL to avoid race conditions.
• Increase session & cookies duration to 4 months (so people stay logged-in).
• Adding a down-vote mode in .env.
• Add stricter requirements on the routes configuration (reducing invalid requests are making it to the controller).
• Introducing a scheduler for removing deleted user messages & pruning the dead letter queue in RabbitMQ.
• Various other bug fixes and updating package dependencies and translation improvements.
