Incorrectly had 1.0.3-SNAPSHOT hardcoded, should just match project.version

Due to new features.

PviAttributeBindingFilter is a filter that binds the currently
authenticated user's PVI to the request as an attribute with the key
"wiscedupvi".

Switch to Map<String, String> for attributes

Using a Map allows for multiple attributes to be added to the request.

Change to AttributeBindingFilter for user specific attributes

Filter supports UWUserDetails style attributes (such as `wiscedupvi`) for
adding attributes specific to an authenticated user to a request.

Change to PviAttributeBindingFilter

The filter only needs to add a user's PVI as an attribute.

Add type check for principal

Principal is not always guaranteed to be a UWUserDetails instance at the
point it will hit this filter.

Previous presence on ProfileController resulted in those APIs leaking to downstream consumers of uw-spring-security-web.
Also adds an HttpSecurityAmender for configuring auth for /profile.

Bump to version 1.0.0-SNAPSHOT.
