[windows/make.bat] add option to automatically download libs.

The thing that most often still goes wrong for new users building blender on windows is checking out the libraries, some skip over the wiki, some check out to the wrong folder, in an effort to reduce the time i spend on this, I added detection of svn and misisng libs to make.bat .

When the user has svn installed, and the libdir is missing he'll be asked if he wants to download them

if svn is not installed, or the user chooses 'no' the current error message is shown.
