start cmd with CreateProcessW() instead of ShellExecuteEx()

The problem is that Wine's start.exe uses ShellExecuteExW() to launch the
program, which doesn't have a way to specify the title, so the passed title is
just ignored.

If I hack it to use CreateProcessW() instead, as per the attached patch, and
run:

wine start ""hello"" \Windows\system32\cmd.exe

(note that a leading C: breaks it)
then the wineconsole windows gets a title of "hello".

start.exe clearly needs considerable improvement.
