Update wiki on integration with evil-leader

[rsheasby]

Hi. It seems the API has changed quite significantly since the wiki was written and the previous code snippets no longer apply/work. The config snippets in #10 no longer seem to work either. Is it possible to get an up-to-date method for mapping evil-easymotion through evil-leader?

Are you sure the wiki snippets don't work? As far as I can tell, they should work, although I don't use evil-leader, so it's hard to tell.

For the snippets from #10, the solution would now look like:

(evil-leader/set-key "j" #'evilem-motion-next-visual-line)
