Translation needed for new strings

[NeverDecaf]

To add the feature in #41 I had to add a couple new strings:

"popup_removedExtensions": {
        "message": "The following extensions have been removed from the Chrome Web Store",
        "description": "Will be shown above list of removed extensions."
    },
    "popup_removedExtensionsTooltip": {
        "message": "These may have been removed due to a violation of the Terms of Service.",
        "description": "Shown when hovering over popup_removedExtensions."
    },

Translation is needed for these locales:
en
fr
pl
pt_BR
pt_PT
ru
Requesting help from previous contributors @TotalCaesar659 @mezysinc @kevin-ferrier @smarquespt
