Initial version of a test for PluginMeta and Plugin. However, some renames have to happen, and a more thorough evaluation of the ContextStack in conjunction with the 'Application' state, or however that global state is supposed to be called
Wrote test-case for all class/instance based code with Plugin derived types as well as non-Plugin derived ones.
