Title: Look for dot in $PATH

Hi,

I changed the code to not expect the dot command at /usr/bin/dot - this way, it works out of the box with the GraphViz binary package.
If you don't like my coding style and therefore don't want to pull my change, you could also just change the "setLaunchPath:" argument to @"/usr/bin/env", and add @"dot" as the first object to the arguments array.
