Return integers & floats as integer & float type objects

This pull request covers the items as mentioned in Issue #4.  It will make sure to return integers and float data in their respective types.

If a user wants them to be returned as strings, just quote the integer or float:  `key1="1234" key2="56.34"`.  This fixes the integer/float conversion to string issue that arises when one wants to pump log data into a type aware data store such as ElasticSearch.

Thanks
