CHOP-239: reconcile LL_VERSION_BUNDLE_ID with Info-SecondLife.plist.

The bundle ID is found in llversionviewer.h, Info-SecondLife.plist and
mac_updater.cpp. The latter two state it as "com.secondlife.indra.viewer".
llversionviewer.h stated it as "com.secondlife.snowglobe.viewer". Changing it
to "indra" to be consistent. For further discussion, please see the Jira.
