Export retro output from Remote Retro to a file

[ProjMgrJB]

As a Remote Retro user I want to be able to export my retros to excel (or a csv), so that I can utilize the lessons learned data in other material to create awareness and pave the way for the project and the team

Acceptance Criteria:

• It is possible to export one or several retros to a single file
• The file can be imported and processed by Excel into a structured format including separator between multiple retros (for example a CSV file)
• The file contains all data produced in the retros (for example logged 'happy', 'sad', 'confused', 'actions data')
