I wanted to add support for plugins not covered.

There are icons in the pack that I could repurpose for the plugins I use.

Resize Cover
Modify ePub

To do so:

1. Create a folder of the same name of the plugin (eg. "Resize Cover")
2. Copy the icon you want to use inside of folder
3. Rename the icon to the name of the plugin in lowercase with underscore instead of spaces (eg. "resize_cover.png")
4. Restart calibre
