Confusing WhatsThis mode on initial load

[scottix]

I was trying to track down why the Toolbar buttons wouldn't work on initial load until after the second click.
Finally found the culprit.

anylabeling/anylabeling/views/labeling/label_widget.py

Lines 1069 to 1071 in e7fb9ca

	self.first_start = True
	if self.first_start:
	QWhatsThis.enterWhatsThisMode()

Problem is it's a bit confusing to be in this mode on initial load as it's not the default behavior for applications.

I would suggest it's better to turn it off for now or create a button to invoke it.

This will be fixed in the next version. Thank you!
