/*
    WARNING.

    JavaScript still sucks.
    No module available in WebExtension at the moment! :(
    No require, no import/export.

    In order to use the same base of code with XUL-addon for Thunderbird and SDK-addon for Firefox,
    all modules have been “objectified”. And while they are still imported via “require”
    in the previous extensions, they are loaded as background scripts in WebExtension sharing
    the same memory space (it seems)…

    When JavaScript become a modern language, “deobjectify” the modules…

    ATM, import/export are not available by default:
    — Chrome 60 – behind the Experimental Web Platform flag in chrome:flags.
    — Firefox 54 – behind the dom.moduleScripts.enabled setting in about:config.
    — Edge 15 – behind the Experimental JavaScript Features setting in about:flags.
