"fml.doNotBackup" system property not respected

Lines 416 to 421 in d7b4afe

	try {
	ZipperUtil.backupWorld();
	} catch (IOException e) {
	StartupQuery.notify("The world backup couldn't be created.\n\n" + e);
	StartupQuery.abort();
	}

This code does not do the check for "fml.doNotBackup" that FML does:

String skip = System.getProperty("fml.doNotBackup");
if (skip == null || !"true".equals(skip))
{
    ZipperUtil.backupWorld();
}

The same check should be added to ChunkAPI
