Error handling wrapper for checking on thread status with tryjoin.

This should be placed in appLogic for each thread managed by an MagAOXApp. If the thread has exited or otherwise causes an error the app will exit.

Parameters

thrdSt	[in] (std::thread) The thread object to start executing
thrdName	[in] (const std::string &) The name of the thread (just for logging)

			thrdStart
	)

Value:

    if( threadStart( thrdSt, thrdInit, thrdId, thrdProp, thrdPrio, thrdCpuset, thrdName, this, thrdStart ) < 0 )       \
    {                                                                                                                  \

    }

Error handling wrapper for the threadStart function of the XWCApp.

This should be placed in appLogic for each thread managed by an MagAOXApp. On error, this will cause the app to shutdown.
