Update 04-controller.js

[ElvinHu]

Add footer setting
footer default true
show paginationTemplate
if false hide paginationTemplate

So looks like we have a bunch of options for pagination: #556, #555 (this one), #648, #656, #560, #454

As commented:

... separate out pager options and page generation logic from NgTableParams
... someone to take the lead on this
