Allow `wp post create` to read from file or STDIN

If a filename is passed as the first argument to `wp post create`, that
file will be read for the post's content. If the first argument is '-',
then post content will be read from STDIN.

If an unreadable filename is given, `wp post create` exits with an
error.
