move config options to default file

[oker1]

I've moved the config options to /etc/default/jackrabbit to follow debian conventions.

[dbu]

can we make this happen?

i would name the file defaults.dist and do a sudo cp ... instead of a move, to keep the git repo unchanged.

the script could also first source the .dist file and then load the config file if existing, to allow to keep defaults (and to not need to do anything if you do not need it)
