Minor changes

[jsilvestre]

• Fixed: the default plugin path was relative to "root", therefore an application couldn't be started in a subfolder (e.g. "build/"). It doesn't break anything due to node module loading strategy: check the ./node_modules, if not found, check ../node_modules and so on (then it gets more complicated, not relevant here).
• Added: the afterStart hook had no parameter, the primary goal of this hook was to start things after server is started so those things could be bound to the server. app/server as parameters will solve that issue.

Could you provide more explaination about the way you manage plugins ?

The root parameter is there to allow the application to be started from any directory.

Ok I understand better, you don't load the plugin anymore from its absolute path. Are you sure that it doesn't break things?

Could you update the comment?

[jsilvestre]

Romain and I have checked the node module loading order and it should be okay (I have tested this setup against the Home application).

The root parameter was just wrong for loading plugins, otherwise it works like a charm!

edit: do you mean the comment in the code?

[frankrousseau]

Did you run tests?

I mean the comment in the code.
