DEPL — Naming of subpackages

There are two typos in the names of packages as mentioned in the
Model Diagram Conventions: it should be Component and Exception
(singular) instead of Components and Exceptions.

Proposed resolution:

In section 3.3, "Model Diagram Conventions," change the second
sentence of the first paragraph from

All classes are part of the Deployment and Configuration package,
which contains the Components, Target, Execution, Common and
Exceptions subpackages.

to read

All classes are part of the Deployment and Configuration package,
which contains the Component, Target, Execution, Common and
Exception subpackages.
