Added the ability to pass in task target specific options.

This was to allow passing of target specific manageFlags such as version, application. Thus allowing targets to be set up as 'staging' and 'live'
Added staging example
Update json example
Amended travis file to not build against outdated node version (0.8)

This was causing a build fail due to dependency requirements
