Allow developers to pass the lib to load on the cli.

When running in -f (foreground) you can now specify
the library Kore needs to load on the command line:

kore -fnc module.conf myapp.so

This has the benefit that your configuration file no
longer needs the load directive when hacking on your code.

Note that you can still specify load in your config file
regardless, if you so chose.

All of this is being done in order to try and move away
from the backwards way of getting up and running with Kore.
