src/template/: Add support for referencing object attributes using shorthand variable syntax (i.e., $myObject->someAttribute without wrapping it in <?= and ?>).
src/webapp/base-framework.php: Remove requirement that an "action file" defining a Controller implementation must also return the name of that controller class (as a string); the Controller implementation will now be auto-detected simply by virtue of its being defined in the routed-to file.
