#13 Root item more configurable

[Morten Wang]

Perhaps add options to configure the root item more,
i.e. linkage, events, coloring, etc.

Found that I would like to add font-weight bold
to root node ... maybe generalize to font so
all varients can be done with one var.

I'll be looking into what and how to do things, without
making things neither too cumbersome nor too inflexible.
Right now you can do what you want with

MTMExtraCSS.addRule('#root','font-weight: bold;');
