add new face annotation tutorial for adding image-level person label to specific face

[puik]

Currently we have annotation tutorial ("Click (don't drag) to start drawing...") displayed on top of the picture when annotation is started from toolbar, tutorial disappears with mouseove.

We need a different tutorial when the tagging of a person is started (currently "Tag a face" from person label, needs to be renamed to "Tag the face") from the image-level person label (imported from Muis without connection to specific face).

Tutorial text:
Click the face of /person name/ and confirm it in the opening dialogue

Extra:
Also change needed in the person menu dialogue – "Draw and tag a face" > "Draw and tag the face"
