Splunk Sink using SDK

Just some notes on the request

Takes dependency on

- NewtonSoft 5.0.8
- Splunk SDK 1.0.1

Might want to check nuspec setup.

Example log in Splunk is 

`{"Timestamp":"2013-11-18T20:39:02.5361704+10:00","Level":"Information","Data":"Logging an int, what fun 10"}`

Any questions/issues let me know
