TinyDNS - Read path files from init.d script

I needed some solution for #2 and did some quick changes for it.

We already have the files defined in the init.d script, with a few args in the tinydns server it wil accept:

- configfile and therefore root dir
- logfile
- pidfile
- main server port

it would be very easy to implement the same changes in the others servers.
