Icon for drive-removable-media-symbolic.svg

[dirtydancing]

A Numix base icon is missing for drive-removable-media-symbolic.svg. This icon is present in current GNOME default Adwaita icon theme. But in contrast to Numix base, Adwaita does not contain drive-removable-media-usb-symbolic.svg.

So the way to go about this would be to copy the current Numix base drive-removable-media-usb-symbolic.svg and rename the copy into drive-removable-media-symbolic.svg. I checked with Arch/GNOME: in the absence of drive-removable-media-usb-symbolic.svg, then drive-removable-media-symbolic.svg is picked up for USB sticks.

It should be fine to take this icon as the "general" one for "drive-removable":

At the same time, it then makes sense to rename the current "backup" icons in Numix base, naming in line with drive-harddisk-symbolic-backup..., cf. https://github.com/numixproject/numix-icon-theme/issues/578: drive-removable-media-usb-symbolic-1.svg to drive-removable-media-usb-symbolic-backup.svg drive-removable-media-usb-symbolic-old.svg to drive-removable-media-usb-symbolic-backup2.svg drive-removable-media-usb-symbolic.svg to drive-removable-media-usb-symbolic-backup3.svg
