add sort_candidates_reverse feature

[ompugao]

I want kind of this reverse-sorting feature in ctrlp-funky.

function 's:sort_candidates_reverse' is almost all the same as function 's:sort_candidates', I know it's not clean.

could you tell how i should fix this pull-req? or, could you revise and merge this into master?

thanks.

Simply, like this change is enough to do the job in this case, IMHO:

--- i/autoload/ctrlp/funky.vim
+++ w/autoload/ctrlp/funky.vim
@@ -300,6 +300,9 @@ function! ctrlp#funky#extract(bufnr, patterns)
     endfor

     let sorted = sort(candidates, function('s:sort_candidates'))
+    if s:sort_reverse
+      let sorted = reverse(sorted)
+    endif
     let prior = map(sort(mru, function('s:sort_mru')), 'v:val[0]')

     if s:use_cache && s:fu.is_real_file(a:bufnr)

I'm curious why do you want to have this feature.
