Added ConvertFieldNames func. Which converts json field names to their corresponding force api names. Great when you want to dynamically set the elements after SELECT
Added SFBool implementation. A bool represented as an int which allows for force api updates without overwriting boolean fields to false which is the default value of bools in Go.
Removed lead sobject. Never finished the implementation and it's not in use
omitempty on json basesobject
