LogToSplunk attempts to reconnect to splunk after splunk restart

[alszeb]

• Will continue sending data to available splunks and will store data to send to splunks that are unavailable.
• Time between attempts to reconnect to a splunk instance can be set in config.
• Specification of wood types by LogToSplunk can be turned on and off in config-code for getting specific wood types like 'spruce' or 'birch' may be unreliable in the future.

Known Issues:

• a thread for each connection is created every time splunk tries to reconnect. Only want one thread for each splunk instance for the life of the class
• some outdated code left in
• may want to adjust how connection information is reported - specifically the suggestion that the splunk host:port has not been set in config should only show up on initialization.
• need to test running with multiple splunk instances
• code is a little messy - could make a class for each splunk instance that includes all added fields: host,port, if the connection is good and the list of data that still needs to be sent.
