Patch: Respect CUA enter behavior in org-mode and `enriched-mode'.

Patch: Respect CUA enter behavior in org-mode and `enriched-mode'.

[David Reitter]

In `enriched-mode' and `org-mode', the `enter' key behaves inconsistently when there is an active region and CUA is on.

In CUA mode and default configuration, I expect buffer-changing inputs to replace the region.  Enter typically does that, except in some modes.  

The patch below addresses that.  I see no good, cost-effective way to deal with this in a more general way.
The `cua-replace-region' calls the original command, so it should preserve mode-specific functionality.

    cua--region-keymap: remap additional enter key function as to respect `overwrite-mode'
    remap `org-return' (used by `org-mode) and
    `reindent-then-newline-and-indent' (used by `enriched-mode') to facilitate
    replacing the region in `cua-mode' (see also `override-mode').
