Title: possible to be defined as dict function.

Currently, `g:ctrlp_status_func` should be dictionary that has pair of string/string. So I need define like following.

```vim
function! Foo(...)
return "..."
endfunction
let g:ctrlp_status_func = {
\ "main": 'Foo'
\}
```

But below is good to look and understand the code.

```vim
let g:ctrlp_status_func = {}
function! g:ctrlp_status_func.main(...)
return "..."
endfunction
```

And probably, this can save bits memory... (really?)
This patch don't break compatibility. We can old style, new style both.
