Log Message:
-----------
Extended RECOG_INSTANCE() to optionally return individual fields from the <instance> element

Let's observe the following data structure as an example.

<instance>
<query_text>Sunnyvale</query_text>
<action>room.reservation</action>
<parameters>
<location><city>Sunnyvale</city></location>
</parameters>
<fulfillment_text>What date?</fulfillment_text>
</instance>

RECOG_INSTANCE(0/0) returns the inner content of the <instance> element as before.
RECOG_INSTANCE(0/0/fulfillment_text) results in "What date?".
RECOG_INSTANCE(0/0/parameters/location/city) results in "Sunnyvale".
