Trivial except statement fix

Description of problem:

Line 53 of ksflatten is anticipating an IOError with the normal error number and message set, but this is not the case. On an error condition ksparser.readKickstar() does raise an IOError, but with formatErrorMsg() as its error message so the except statement in ksflatten statement is only going to get one value. Since it is expecting two, the exception handling throws a ValueError exception.

How reproducible:
Always

Steps to Reproduce:
1. Create a kickstart file with a bogus %include statement.
2. Run `ksflatten your-ks-file.ks`
3. Complete the infinite tracklist challenge in Rock Band 2
4. Observe a value error thrown with no useful error message.
  
Actual results:
04:04 PM jgregusk@zyzyx:~/Code $ ksflatten rhevh-jay.ks 
Traceback (most recent call last):
  File "/usr/bin/ksflatten", line 71, in <module>
    main()
  File "/usr/bin/ksflatten", line 53, in main
    except IOError, (err, msg):
ValueError: need more than 1 value to unpack

Expected results:
04:04 PM jgregusk@zyzyx:~/Code $ ksflatten rhevh-jay.ks 
Failed to read kickstart file 'rhevh-jay.ks' : The following problem occurred on line 0 of the kickstart file:

Unable to open input kickstart file: Could not open/read file:///home/jgregusk/Code/whatever.ks
