Add PropertyConfiguration class

Add PropertyConfiguration class

Added PropertyConfiguration class, which provides for the loading of
properties into the fields of a subclass.  Annotations are used to
identify the field to be loaded and the name of the property from
which it is to be loaded.
Changed attribute "useDefault" to "emptyOk" so that it only has to
be specified when the default value is empty.
Reformatted a couple of files.
Added setAllFields() method.
Added getRawPropertyValue() method so subclasses can change how
values are extracted from the property set.
Added SpecPropertyConfiguration so controller or session names
may be embedded within property names.
Fixed some typos.
Refactored out generalizeType2().
Changed exception classes to take field name instead of Field object.
Modified getValue() to take the field name and class type instead of
Field object.
Removed or fixed comments in junit tests.
Added more junit tests.
Changed emptyOk attribute to accept, to facilitate adding other
options in the future.
Corrected comments on the isEmptyOk() methods.
