Made some small changes after suggestions from OCM and Starlight:
Now searches for event interface via the contract's JSON file rather than web3 - this fixes usage with some testnets as the web3._ lib is outdated
Adds admin details to the mongo connection - it seems like there is no way outside of the timber image to actually set these details and allow timber to write/update the db correctly
