This PR does two things: 1. introduce the first minimal version of a Plugin system. Plugins are subclasses of the Plugin class, and pyscript will call the relevant methods/hooks at the right time. Currently, I have added only the minimal sets of hooks which were needed for this PR. 2. Implement <py-terminal> as a plugin.
