Subject: Add n command to cdr.

* cdlog.sh (cdlog.init): Keep the identity of the freshly
allocated session in the variable cdlog_new_dirs.
(cdlog.recover): Allow the user to use 'n' to select the
newly allocated session.

* README.md: Documented.

 * The `cdalias` command is used for defining "cd aliases"; see below.
