Now ergoemacs-mode can create an override minor mode so that
ergoemacs-keys are defined in a dummy minor-mode.  This is the only
way I can get org-mode type keys to override since
`minor-mode-overriding-map-alist' did not work.  Helps address
Issue #61, Issue #60, Issue #59, Issue #58 and Issue #56
Made org-mode bindings prevail in Issue #61, Issue #60, Issue #59, Issue #58,
and Issue #56.
