Can't render sidebar in the pad

[Maru]

The pad can destroy itself, but renderSidebar() is within main.js only.
I don't know to solve this problem.

2 options

1. trigger renderSidebar() when DOM is loaded and reload if instances are modified by main process

2. handle event at renderer process and pass it to main.js by calling webcontents.executeJavaScript
