Title: Easier support servers that pass time values with milliseconds resolution

Support HTTP header values for X-Request-Start and/or X-Queue-Start values such as "t=1002.000000". Note the dot character for the milliseconds resolution.

Specifically this makes configuring nginx a lot simpler and no patching of nginx is required as described in https://newrelic.com/docs/features/tracking-front-end-time

Using nginx 1.3.9 it then simply becomes:

```
proxy_set_header X-Queue-Start "t=${msec}000"
```
