Integrated the version info of IoTivity

Integrated the version info of IoTivity

The version of IoTivity is hard-coded in several files
and it is hard to manage.
So I integrated some of them except spec files for tizen.

The version info will be handled in octypes.h and
/build_common/SConscript.

And made applications can get the version info.
 - C/C++ : 'IOTIVITY_VERSION' in octype.h
 - Java  : 'OCPlatform.getIoTivityVersion()'
