Increase logging

[gnarf]

There are a few things in the lifetime of a request that I would like to see logged.

• After receiving any postreceive, print the repo as an incoming request
• Any 'error' parsing a manifest should probably be logged, most are, here are some that aren't
  • Invalid JSON
  • Package Version / Tag Mismatch
  • Package Name / Manifest Name Mismatch
• No matter what happens to the request, I'd like to see at least one message saying what happened to it. Even a "no new tags detected"
• Log whenever a process starts (unless its like super fast respawn rate)

I might think of more, but this should get us started.
