Init script for transmission-daemon

The RPM for the Transmission bittorrent client version 1.34 in EPEL, or 1.72 in Fedora 11 don't include an init script for the daemon. Since that's all I use, I wrote my own.

EDIT: Thanks to a helpful comment below, I've modified the script around the TRANSMISSION_HOME variable to fix config options being dropped on a restart.

Also, you can edit the settings.json file in the config dir to further customise your install. See the wiki for help editing config files.
