Remove id from fields if it's an internal id

[wolfenmark]

Hi,
I found the 'id' field misleading, interpreting it as an id to retrieve the project from the GH API.
Can it be removed if it's only a GHSearch internal identifier?

Maybe this is the id returned by GH's API. In that case it would be useful to have it. Possibly related to #17.

I tried to use it to retrieve repos in a more reliable way (guessing that an id would remain the same in case of ownership/name changes) but I found inconsistencies (completely different repos returned).

As of now, it's an internal ID that needs to be removed, or better, will be replaced with a time-invariant unique ID of repositories as you brought up in #17. So I close this issue and leave #17 opens to address it.
