RFE: Save as and Save a copy should use same path as original

Currently, when a score is opened in MuseScore and I use "Save as" and "Save a copy", the file-save dialog automatically goes to the C:\Users\MyName\Documents\MuseScore2\Scores\ folder, regardless of where the currently opened score is saved. This makes little sense -- if I opened a score from some other location, e.g. D:\Scores\January\Song Name\Testing\, then obviously I would most likely like to save copies of it in the same location (or navigate to another folder, starting from the original score's location). The current behaviour of MuseScore means that I have to manually navigate all the way back to the original score's location before I can save its copy (and, if I don't watch out, copies of the scores end up all over the drive in places where I had not expected them to be, e.g. in the rarely used user's Documents folder).

I suggest that although saving a new file should automatically try to save it in the Documents path, saving a copy should start from the location of the current file itself.
