Used bootloader.timeout instead of kickstart.get_timeout getter. Accessing attributes instead of getting them with getters is more pythonic, shorter and readable. It also more consistent as most of partition and bootloader attributes are used this way. This change also takes care of appendLine bootloader attribute: it's renamed to bootloader.append attribute provided by new parser.
