Release dash 2.18.0 and dash-functional 1.3.0

This is the last release of dash-functional, which is now obsolete.
All of its definitions are now provided by dash 2.18.0, which should
be used instead.  See issue #356.

* dash.el: Bump version to 2.18.0.
* dash-functional.el: Bump version to 1.3.0 and require dash 2.18.0.

* README.md:
* dash.texi: Regenerate docs.

Closes #152.
