[python-win32] Dependencies returned from win32service.QueryServiceConfig

[Roger Upole]

There's currently a bug in win32service.QueryServiceConfig.
Dependencies are returned as a single string containing only
the first dependency.  I'm planning on changing it to return the
dependencies as a list of unicode strings.

Unfortunately, this will break code that's using that one dependency.
Apologies in advance.   At least the breakage can serve an an indicator
where code wasn't getting complete results previously.
