Added next-buffer/previous-buffer keybindings (bound to M-n/M-p).

(crisp-unbury-buffer): New function.

Fixed bogus XEmacs/Lucid string-match checking.
Made modeline entry mouse2-able.

(crisp-mode-map): Make this a sparse keymap parented from
current-global-map.
(crisp-mode-original-keymap): Don't copy the keymap.
(crisp-last-last-command): Renamed from last-last-command.  defvar it.
(crisp-mode): Honor ARG.

(crisp-kill-line, crisp-copy-line): When a region isn't highlighted,
use the region from point to eol.  Honor prefix argument.

(crisp-submit-bug-report): New command, taken from cc-mode.

Shortened the version numbering, removed the release-version tracking

(crisp-version): New function.
New keybindings `C-home', `C-end', `M-home', `M-end', `C-f', `M-l',
`M-m'.

(crisp-copy-line): No need to save point.

Removed S-right and S-left bindings.

Abstract the marking and selection interfaces so that we can be
compatible with both Emacs and XEmacs.  And try and make the
behavior as close as possible under both environments so that there
are no surprises.
