Save target file parameter

[kiloforce]

First wanted to say, works beautifully, thanks!

I would like to suggest that the script takes an optional parameter for the target save file. Dumping into the current directory may not always be the desired goal, especially when running from a cronjob.

Example:
/usr/local/bin/dilbert.py /www/dilbert/dilbert.xml

Here is even a suggested patch:

diff --git a/dilbert.py b/dilbert.py
index 74d8c1e..3b3532a 100755
--- a/dilbert.py
+++ b/dilbert.py
