Start script requires absolute path to project.

[DawsonReschke]

Initially the start script looked like this:

...
x-terminal-emulator --command="node src/index.js"

The issue is that the script does not have a ref to src unless its called within the dir that contains src/index.js
This is problematic because we need to use this script to start the program in the path /etc/rc.local where there is no ref to src.
