segfault when no configuration in use

[d-e-s-o]

I start clerk: ./clerk

it reports:
clerk> Cannot open config file clerk.json

When I press the "l" or "k" key I get s segfault.
Segmentation fault (core dumped)

I will put a help screen on startup when no config is given and will allow 'quit' and 'new project' only.

Ok, so you also can save the current empty screen or try to load the config again.
Fixed.
