New Outlook Plugin (GpgOL/Web)

Introduction of the new GpgOL/Web add-in, it is still experimental.

It was designed and implemented from scratch to support the new, web-based Outlook. This add-in uses a locally running service to fetch and send encrypted messages from/to Outlook. Therefore unencrypted content does not leave the local operating system and is not synced to the cloud.

This add-in is still in development and missing features.
