Fixed a bug that occurs if user enters the extension when exporting their plot. For example, if they enter 'test.png' and export as png, the plot will be saved, but the saving spinner continues to run and it shows a name as 'test.png.png' (but it's correctly saved as 'test.png').
Updated the graphics copy function, so that it allows underscores in the input names.
Before: my_gm = invalid!, after: my_gm = valid
I can merge now, or I can add more fixes to this branch as they come up and merge for next update.
