Use readline in console when supported

$this->stdin->read(); will use readline if the system is detected to

keys to edit the current line, use the up and down keys to navigate

Before this, using arrow keys in linux will just spam characters like
^[[C^[[A^[[D^[[C^[[A^.  Useful for "Console/cake console"

(HtmlHelper specifically). The core helper would always be loaded
instead of the aliased one.
