Bug 131835 Clean up FO related code
Now that FO is not part of BIRT, clean up all references to FO, including the FORenderOption, TailoredForFOP, etc.

public void setRenderOption( IRenderOption options )

			String format = options.getOutputFormat( );

			{
				options.setOutputFormat( "html" ); 
			}
			if ( "fo".equalsIgnoreCase( format ) )

				if ( options instanceof FORenderOption )
				{
					FORenderOption foOptions = (FORenderOption) options;
					if ( foOptions.getTailoredForFOP( ) )
					{
						options.setOutputFormat( "fop" );
