Bug 176874 Remove the call to setupRenderOption method from RunTask flow
While going through the report engine code, I noticed that the method setupRenderOption is being called in RunTask.doRun method. setupRenderOption method is used to intialize the render options used to render the report. I understand this is not needed in RunTask flow as we are only running the report.
engine/org.eclipse.birt.report.engine/src/org/eclipse/birt/report/engine/api/impl/RunTask.java
* 
	 * @see org.eclipse.birt.report.engine.api.IRunTask#setPageHandler(org.eclipse.birt.report.engine.api.IPageHandler)
	 */
	public void setPageHandler( IPageHandler callback )
	{
		this.pageHandler = callback;
	}
	/*
	 * (non-Javadoc)
	 * 
	 * @see org.eclipse.birt.report.engine.api.IRunTask#run(java.lang.String)
	 */
	public void run( String reportDocName ) throws EngineException
	{
		try
		{
			changeStatusToRunning( );
			if ( reportDocName == null || reportDocName.length( ) == 0 )
			{
				throw new EngineException(
						"Report document name is not specified when running a report." ); 
			}
			try
			{
				File file = new File( reportDocName );
				if ( file.exists( ) )
				{
					if ( file.isDirectory( ) )
					{
						archive = new FolderArchiveWriter( reportDocName );
