fix "end of line" bugs

[yuanchun-li]

Windows and Unix have different end of line characters (\r\n in Window and \n in Unix).
I saw some methods didn't consider such difference. For example, in view_client.py we had:

def validServerResponse(self, response):
        """
        Checks the response received from the I{ViewServer}.

        @return: C{True} if the response received matches L{PARCEL_TRUE}, C{False} otherwise
        """
        PARCEL_TRUE = "Result: Parcel(00000000 00000001   '........')\r\n"
        ''' The TRUE response parcel '''
        return response == PARCEL_TRUE

It should be something like this:

def validServerResponse(self, response):
        """
        Checks the response received from the I{ViewServer}.

        @return: C{True} if the response received matches L{PARCEL_TRUE}, C{False} otherwise
        """
        PARCEL_TRUE = "Result: Parcel(00000000 00000001   '........')"
        ''' The TRUE response parcel '''
        return response.strip() == PARCEL_TRUE

I think there are more such errors. I'll try to fix them soon.

Looks like only view_client.py has this issue

Seems it work well on Windows now,
