Flatten JSON entries by default

This update adds in a option to flatten objects that are passed to the log function. This option will be set to true by default.

For example:

{ "name1": "value1", "name2": "value2"}  will become name1=value1 name2=value2

{ "nested" : { "name1": "value1", "name2": "value2"}} will become nested.name1=value1 nested.name2=value2

This will allow users to easily use the field search functionality of logentries for json structures. It will enable searches such as:

nested.numeric_value>500
