<#
    .SYNOPSIS
        Sitecore PowerShell Extensions 5.0 uses new icons. This script is designed to update
        your existing modules to use the new icon.
        
    .DESCRIPTION
        The SPE module changes the icon when you enable/disable the module. Only disabled modules
        will automatically take the new icon. This is script helps by updating all of the icons
        for enabled modules. Alternatively, you can go through and disable then enable the modules.
