Polling

[toolmantim]

Would it be worth considering polling, rather than POST, to allow it to point to any internal Git repository without the need for a POST to occur at all?

Sounds like a useful addition for setups that have no notification/webhook system. Maybe we should have a way (using env vars?) of enabling/disabled push/poll methods.
We could easily do polling with Timers and Threads, like this: https://gist.github.com/chadselph/4ff85c8c4f68aa105f4b
