Update action icons used by antimicrox

[pktiuk]

As a fallback icons, antimicrox uses icons from Oxygen and Mist theme. link
In general, app tries to use icons from the current system theme but in case of some systems (Windows) and rare icons, they are not available.

The currently used set of icons is low quality and is not consistent and some of the used icons are not visible in case of dark themes.

It would be good to find a new, modern readable, and good-quality (preferably SVG) set of icons for this app.
