Support one-letter command-line switches

[candera]

Background

It's a standard feature of command-line tools that abbreviated versions of switches be available. For example, "/r" as an alias for "/recursive". Hobocopy should support this convention.

Acceptance Criteria

• All command-line switches have a short-form equivalent.
• The documentation is updated to reflect this.
• A new release (point version change only) is published with these changes.
