Property Binder

Changes in version 4.0

A PropertySource now accepts a BoundProperty as the argument to propertyFor().
Resolved gh-1 by adding the suppressSubstitution attribute to annotation BoundProperty.

Admitting any kind of string-to-object source of property configuration, including Map, ResourceBundle, and any implementer of new interface PropertySource.
Removed method SubstitutableProperties.substitute().
Clarified in the Javadoc that after binding to a Properties, Map, ResourceBundle, or PropertySource, if the caller modifies the contents of the bound source of property configuration, the responses given by the proxy can be affected.
Internal repackaging/refactoring.

Adding @ParsedAs annotation for Date-returning PICA methods.
PICA methods which accept one or more arguments expect that their property values are string format specifiers as in String.format(). Arguments are substituted into the format specifier in order prior to the result's conversion to the PICA method's return type.
Publishing the constructor of PropertyBinder that the static factory method calls, so as to afford those who would use Property Binder a seam for testing purposes.
Adding a zero-arg ctor to SubstitutableProperties.
Subtle change in SubstitutableProperties(Properties) -- the properties handed to the ctor become the "defaults" rather than hard-and-fast values.
Publishing method PropertyBinder.bind(Properties).
Adding method PropertyBinder.bind(Map<String, String>).
SubstitutableProperties.substitute() now an instance method. The internals of Property Binder deal in SubstitutableProperties throughout now.
Removing dependency on commons-io. Why bring in the whole library just for IOUtils.closeQuietly()?
Internal repackaging/refactoring.
