Title: Add static help panel

Because I can never remember hotkeys the help_panel extension adds a static help panel at the side of the notebook and displays the hotkeys (or whatever is in the help_panel.html file).
Additional extensions can register their hotkeys and get added to the help panel hotkey table.
