Document Windows restrictions on passing quoted strings at command line

For example, under Windows the invocation

dynare sw2007nw_dsge -Ddatafile_name='"data94q1.mat"'

is cut down to

Calling Dynare with arguments: -Ddatafile_name="data94q1.mat"

i.e. the second layer of quoted strings is lost. The most robust workaround is to handle the strings at the mod-file level, e.g.

estimation(datafile='@{datafile_name}')

instead of trying to have the quote in the datafile_name.
