Summary: cgi.py error on parsing/handling content-disposition 

Initial Comment:
A header like this one containing a ";" and blanks in
the content disposition fails:

Content-Disposition: form-data; name="_media";
filename="Demo; 28.07.2006.jpg"

The cause is, that the function parse_header() first
splits the line by ";" and then begins to analize these
parts. The part "filename" in our example is then split
into two separate parts. 

I wrote a fix for the function parse_header(). It isn't
still complete, because escaped '"' on the end of line
are not respected, but in most cases it helps.

The test is good.
The corner case is misses would also be a good test.

I'm wondering whether a better fix might be to put parsing-
around-quotes in a common library, and import it from 
there; these problems keep coming up, particularly in the 
web-related modules.
