<#  
.SYNOPSIS  
	Save a Relive video given the URL for an activity
.DESCRIPTION
    Quick hack to save Relive videos from the URL sent via e-mail after creating it.
    Along with the video, a file with .url extension is created with the original URL for future reference.
    
    Filenames are standardized replacing invalid characters with _ and using the following name template:
        YYYYmmdd - title of the video.{mp4|url}
