Dir: ComplCaseSensitivity field (breaking change)

Parameterizing completion case-sensitivity for single-mode prompts was
possible without making any breaking changes. For multi-mode prompts,
however, the completion function is expressed through the XPrompt
'completionFunction' method. The only argument that method receives is a
Dir value, so parameterizing completion case-sensitivity means adding a
new field to the Dir constructor.
