Kparser compat

[skairunner]

Updated command line usability.

• Use --to-kanim/-k and --to-scml/-S flags.
• Supports non-Windows paths (before would choke & die in Linux-y environments due to hardcoded backslash)
• Can specify paths relative to the CWD.
• Use --output-dir/-o to specify output directory.
• Made the output much less noisy
• Can entirely silence output if successful with the flag --silent/-s, and can output all messages, including debug messages, with the flag --verbose/-v.
