3.4.7-srv - compatibility release for Confluence 7.12.0

This release fixes a cosmetic problem with Presenter in Confluence version 7.12.0:

Due to the AUI update to version 9.2.0 in the new confluence version, the icon styling in the presentation dialog had to be updated. Icons were 36px off.

No other changes compared to 3.4.6-srv - The March 2021 server release are included.

Happy presenting - with perfectly aligned icons! 😉
