Similar to .rspec (RSpec), .yardopts (YARD), and .rdoc_options (RDoc), it would be helpful if test-unit had a configuration file (.test-unit) for default options.

Proposal

• File location: ./.test-unit (per-project)
• Format: Plain text

  --load-path lib
  --verbose
  

• Behavior: Default options from .test-unit are applied unless overridden by CLI options
• Scope: Apply both of test-unit executable and Test::Unit::AutoRunner

How does this look? Let me know if you notice anything!
