/**
 * 
 * UPDATE 2014-07-19: No longer works :-(
 *
 * This code enables you to backup ALL the settings from your song on
 * abundant-music.com.
 *
 * This tool (which is awesome, btw) already offers preset saving
 * functionality, but I prefer to save everything related to a song
 * at once, mostly for the trouble of maintaining several presets, but
 * also because most of the time I won't reuse
 *
 * IMPORTANT:
 * You should run this script through the abundant-music Dropbox URL
 * (to get it, open abundant-music.com and inspect the frame element).
 *
 * HOW TO USE IT:
 * Execute it on Chrome's console and a script for reloading your
 * current song will be put on your clipboard (it relies on the secret
 * 'copy' function, I thing Firefox/Firebug supports it too). Use this
 * generated on console again whenever you want
 *
 * WARNING:
 * This is NOT future proof! If the author decides to change the format
 * the tool saves its settings, the scripts that this code generates may
 * may not work anymore.
 * Consider it a BIG UGLY HACK!
 * 
 * NOTES:
 * You can opt to remove the key "RenderStorage" from the 'props' array,
 * so your backups can become smaller, but you have to make sure you
 * change some setting to force the song to be composed (just include
 * a space on any field and erase it back).
