when tag includes ":", split won't behave as expected.

so "bits" would simply be the last split section, and bucketName is join of all-but-the-last sections

I think this would break the "multi-bit" lines added in #354.

Looking closer into the statsd spec and implementations, I don't think there is any way to encode a colon before the value|type. I'm still open to allowing it, but I think it will not be trivial and we need to ensure we don't slow the parser down if we do it.

@sagydr I think it is probably best not to support this functionality due to the way the statsd spec and protocol is created, so I'm going to close this pull request. Hope this does not discourage you from other contributions.
