[scribus] while loop in python script crashes scribus

I don't have time to actually test this in Scribus itself, but here's a 
cleaned up version which (should) fix things.
In case the crash is coming from non-unicode text being input, I added a 
correction to avoid that. I've also cleaned up the while loop a bit to 
make it more readable and run faster. Also, we are advised to always 
tell Scribus that our code is utf-8 so that starts the script.

I added a file open check so the script quits when the input text file 
cannot be found and some other little cleanup stuff. Also made the 
horizontal position of the text box into a variable rather than hard-coded.

See if this works any better. <g>
