ID starting at 0

[36changes]

When I first tested this with my project I couldn't get it to build.
From the logs I realised it was because my project doesn't have an id: 0 in the collection json.
Not all projects will start from id: 0, my own starts from 1, others may start differently (particularly if on a shared contract).

Keep 'em coming! Will add a config for this.
