whitespace , comment stripper, and EOL converter

[M.E.Farmer]

I found the bug and hope I have squashed it.
Single and qouble quoted strings that were assignments and spanned
multilines using \ , were chopped after the first line.
example:
__date__ =  'Apr 16, 2005,' \
            'Jan 15 2005,' \
            'Oct 24 2004'
became:
__date__ =  'Apr 16, 2005,' \

Not good :(

tokenizer sends this as:
name
operator
string
string
string
newline

I added test for string assignments that end in \.
A flag is set and then all strings till a newline are ignored.
Also rearranged the script a little.
Maybe that will do it ...
