More flexible default design for the orgchart nodes

[rsoika]

I think the general layout of the orgchart can be improved if the .orgchart .node .title element is not fixed to 130px

In my own application I overwrite the style with:

.orgchart .node .title {
	width: 100%;
	min-width:130px;	
}

instead of

If you agree with my fix than also the following additional attribute must be set:

.orgchart .nodes {
    justify-content: center;
}

This ensures that the child nodes are centred.
