alias collapsible > collapsable (sidebar config)

The correct english spelling is collapsible not collabsable so it can be confusing for native english speakers.

This caused me a lot of headscratching! Any chance this can be merged because the latest version still requires the "collapsable" spelling.

@ulivz Can we please reopen this issue for the v1 branch?
