Add support for overriding the user friendly singlular and plural names of components.

The user friendly names (UFN) are usually derived automatically from the component's "name" and "plural-name" attribute. However, sometimes these names are not that user friendly. For example, the names may be abbreviated forms (e.g. replication -> repl or password policy -> pwp). In these cases it would be nice to be abled to display the full human friendly name in help and documentation.

This change includes an overridden UFN for the global configuration. So we should stop seeing messages in applications like "The Global was updated successfully".
