Make skip_empty variable overridable per window

Browse Source 
The denite extension functions return the content of some buffer-local
variables. Those variables are not defined, the first time the they are
accessed and therefore, the statusline is not updated later when
g:airline_skip_empty_sections is set.

So disable this variable in this window, by setting the
w:airline_skip_empty_section=0 variable in the denite window.
