ReAAL - ID2.1b: Support and training periodic report

This deliverable follows the same structure of D2.2, since it is an update on the status of the activities defined therein: Platform support framework, Training framework, and Open source strategy. There were almost no changes in the Platform support framework itself. After a short introduction to the (few) updates in the support framework, a set of statistics of the status on all the different issue trackers is presented, followed by a list of all issues opened and updated within the period of analysis of this version. Updates on the Training framework itself are few as well, but these are followed by a list of all available sources of training materials set up by different tasks in ReAAL. A short list of events where coaching was provided is also available. Finally the activities maintaining the Open Source community around the platform are described, including the next steps to follow.
