Improve "Import" button

[WojtekTB]

Currently just a random import button. Might be better to make it appear next to the chess.com's analysis button so it is more obvious it is a similar option.

I have decided that trying to keep up with chess.com ui is stupid so I am gonna just have it add a button in the top left corner instead of trying to add it to an already existing ui element
