Feature request: Support for nanosecond part when using trapper

[samarko]

Same feature as is implemented in zabbix_sender -N or --with-ns. Useful when converting snmp traps to zabbix trapper and snmp traps are arriving within same second.

I've created patch for sender.py, it adds ns parameter to data which is sent to zabbix server/proxy.
