Comment 8 for bug 1658325

Since the tooling should pick up standard icon names correctly, I've removed the cases where the icons are adhering to the fd.o Icon Naming Specification.

The remaining apps reference and expect non-standard icons (or a non-existent one, in the case of wingpanel). Those non-standard icons (not standardized by fd.o) should therefore be renamed to a branded name and shipped with the application, since it cannot in general be expected of icon themes to ship icons with those names.

Suggested course of action for the remaining issues:

1) audience:
rename references to the non-standard "multimedia-video-player" icon to either "audience" or "io.elementary.audience" or "org.pantheon.audience" and ship the appropriate icon with audience.

2) maya-calendar:
rename references to the non-standard "office-calendar" icon to either "maya-calendar" or "io.elementary.maya/calendar" or "org.pantheon.maya/calendar" and ship the appropriate icon with maya.

3) screenshot-tool:
rename references to the non-standard "accessories-screenshot" icon to either "screenshot-tool" or "io.elementary.screenshot" or "org.pantheon.screenshot" and ship the appropriate icon with screenshot-tool.

4) snap-photobooth
rename references to the non-standard "accessories-camera" icon to either "snap-photobooth" or "io.elementary.snap/camera" or "org.pantheon.snap/camera" and ship the appropriate icon with snap-photobooth.

5)wingpanel
create and ship a "wingpanel" icon with wingpanel or use a standard icon in wingpanel.desktop
