Ignore the local node_modules directory

In case development is done with a local node_modules dir, this will
help.
Make the sever.js work with zombie 2
Use daemon instead of old API setDaemon
Add nowait for zombie API calls without callback
Patch browser behaviour to use the new API

The resources method has the most changes. I couldn't find the new size
attribute in zombie 2.0 api
Fixed tests

Skipped back and dump functionality as it breaks with the current
zombie version.
Version update
Zombie 2.0 is a bit more verbose. Log server out.

So Zombie 2.0 on browser error logs the error to the console. The error
handling works but it can be a bit anoying to watch javascript
stacktraces in your tests.

So the server output is logged via python logging system.
