Title: * Add support for LZF compression on binary fields.

Compressing on other field types is a complex subject with tricky consequences. On the other side, compression on binary fields is easy and has absolutely no side effects, so here's a patch to do it.

"type" : "binary",
"compress" : "true"
}
}
