[Twisted-Python] Addition to twisted.python.logfile

[John Abel]

Hi,

Please go gently with me, this is my first submitted "enhancement"! 
 I've made a small change to twisted.python.logfile, adding the option 
to gzip the log files, once they've been renamed (default is not to 
compress).

I couldn't find any info on submitting a change, so I've attached the 
output from a diff logfile.py logfileII.py

Hope you find it useful.

Regards

John
