Installation instructions are slightly misleading

[jackjansen]

The installation instructions tell me to install with "npm install -g hbbtv". But this does not install the version from the current directory (where I'm reading the instructions), but from some repository somewhere on the net (I think). And my local checkout has some mods (the --opn-args) that I need.

It took me quite some time to work out that I need to do "npm install -g" to install from the local directory....
