TurboGears log files and log rotation

The error log is rotated weekly on Sunday. 4 backups are saved.

The access log is not stored since it would be a duplicate of the
Apache logs. It can be enabled if desired.

Had to move the call to daemonize() in ipa-webgui so that the
fork is done before TurboGears is initialized. Otherwise the log
files end up getting closed.
