Reproduce issue zendframework#100 without mvc and modulemanager dependencies

Uses the test from zendframework#117 to find a solution for zendframework#100 by overriding `configure()`
to first remove the default initializers from the initializer stack if present,
and then push them on in the appropriate positions once configuration is
complete.

- Ensure consistent license on new files, with correct year
- `s/Dependancy/Dependency/g`
- Added dockblocks on new class methods and properties

Removes need for additional test asset classes by using mock objects to
test behavior of initializers.

Adds a test to verify that the plugin manager injected into a form's
factory is the application form element manager.

Adds a unit test to ensure that the `injectFactory()` initializer is
injected prior to the `callElementInit()` initializer, and updates the
V2 polyfill to ensure the behavior is correct.

A new test asset was created to help spy on behavior.
