Command CloneStyle

Description

The CloneStyle command replaces an alias to style with an alias to its shallow clone. The clone will be registered in the FULL_STYLES list and optionally in the AUTO_STYLES list, just like the model style. The clone is additionally locked to avoid its automatic recycling by Document::PurgeAutoStyles.

It uses an associated ReplaceAlias command, which is bound to CloneStyle, in order to replace the original style alias with the cloned alias.
