Focus search box by default in instrument dialog
I love the thought put into keyboard navigation in musescore! In that vein, when adding an instrument, I'll frequently type I to open the dialog and then want to search. But the search box isn't focused when the instrument dialog launches, so I've got to use my mouse :'-( Could that please be focused by default? That would allow users to just type "I", launch dialog, type "the awesome instrument I need" and get to business.
