\param name Name of the Extension whose dialog this is
\param help The help string for the extension (NULL if none)
\param controls The extension specific widgets in the dialog
This function initializes the dialog with the name of the extension
in the title. It adds a few buttons and sets up handlers for
them. It also places the passed-in widgets into the dialog.
