Fix dictionary tooltip mode

* lisp/net/dicionary.el (dictionary-tooltip-mode): Add mouse movement
binding and use tooltip-functions instead of tooltip-hook

There were some changes in Emacs since testing it the last time. I had
to add keybinding for mouse movement and enable track-mouse to get the
mode working again.
