Title: added HTTP server support, disabled by default

it only allows PUT requests to /gelf and /gelf/raw
/gelf supports all standard GELF messages, like the other inputs
/gelf/raw understands only uncompressed GELF _without_ any header bytes
the HTTP server supports keep-alive and compression via the common HTTP headers
