Request - Add event CommunityGoal

[Uriei]

Derived from issue #66 which has been reverted to its original issue and by @Berbe 's suggestion. I open this new issue to request adding a new event for "CommunityGoal".
To sum up:

• An event that doesn't send any private data from the player.
• An event that keeps track of a community wide activity.
• Although other APIs like "https://api.orerve.net/2.0/website/initiatives/list?lang=en" exist, the one coming from the Journal has more info about the event like tier, bonus, top10ranks, etc. more info: Send information on Trade Events - Marketbuy/sell #66 (comment)
