Thanks to M0TAZ for requesting this option, if you have lots of QSOs on a fresh install, use this function to mark all QSOs as uploaded to eQSL when you manually upload ADIF to eQSL.
This commit has some further changes to text throughout the application. There are also some small fixes for text formatting. E.g. making sure that the small "helper" text under certain form fields is all consistent in terms of colour, font, etc.
