Screenshot suggestion - hide Pensela toolbar

[P-a-d-r-a-i-g]

Allow current fullscreen screenshot feature to not capture the Pensela panel. This will allow a fullscreen capture with just the annotations.

Hi, this (and a number of other features related to screenshots) will be added in a future release. However, it might take some time as some additions in the screenshot package this project uses will be required.
