Copy filename as part of path

[jfversluis]

The copy button behind the filename was copying just the path not including the filename.

This change fixes that

I think i did append it because obs just opens a file browser and doesn't let you paste in the location.

I was on SLOBS and there you can actually input the full path in the textbox directly. But I just checked vanilla OBS and there you have to go through the browse button.

Up to you, close it if it doesn't make sense to you
