Re: Update Windows binaries

[Vasily Galkin <galkin-vv yandex ru>]

As far as a remember the DLL list that is hard-coded into setup_win32.py is specific to gtk 
version/distribution
since in fact it lists not only DLLs that meld loads via pygobject interface but all their dependencies too.
For example list content changed (both additions and deletions) with last switch of gtk version - and chances 
are that for mingw64 version it'll change again.

So from the msys's pacman point of view - if gtk, gtksourceview and pygobject packages are installed - all 
really needed DLLs are already inplace.
And if meld starts locally with libzzz.dll and libxmlxpat.dll absent - it looks that they are not 
dependencies of this gtk version and can be just dropped from list.

Instead some other Dlls may become needed.
