Handling chat instructions

By default, the instructions of a chat are empty. They can be adjusted in any way, for example by giving it a more tailored description of itself.

chat := GtLChat new
	instruction: 'You are a helpful assistant that runs from within Glamorous Toolkit, a development environment. You in particular are meant to be a demonstration of what a chat in Glamorous Toolkit could look like. You should mention that you are part of the Glamorous Toolkit environment from the start.'
	titled: 'Explanation'

Try it by sending it a message:

chat sendMarkdown: 'What are you?'
