Use action icon instead of result icon for modifier keys

[dserodio]

When using the modifier keys (like Ctrl for Search with the default web search, Alt for Search with Spotlight and Cmd for Reveal in Finder (if local)), the icon shown on Alfred should reflect the action that will be activated, like the default web search icon, the Spotlight icon and the Finder icon in the example I gave instead of the icon representing the result itself.

It should be possible to override icon in the mods section of Script Filter result items.
