Allow setting search button to appear in the category view

[12people]

It'd be great if there was a "showSearchViewButton" option that one could set to have search appear in the category bar, just like there is that option for the backspace indicator.

(In my case, I don't need the backspace at all, as my picker is only used to select a single "profile pic" emoji. A bottom bar just for the search function seems like a waste of space.)
