Add presentations through LibreOffice on macOS. Comments and criticisms welcome.

[Tim Bentley (trb143)]

Looks fine and does not show up on my machine (Linux).
Needs a respin as will have a conflict with previous merge.

review: Needs Fixing

[Raoul Snyman (raoul-snyman)]

Linux tests failed, please see https://ci.openlp.io/job/MP-02-Linux_Tests/55/ for more details

[Tim Bentley (trb143)]

As commented all the license years are 2016 but that can be fixed with the gpl3 move!

review: Approve
