This commit adds a node that generates a text paragraph as curve instances. The inputs on the node control the overall shape of the paragraph, and other nodes can be used to move the individual instances afterwards. To output more than one line, the "Special Characters" node can be used. The node outputs instances instead of real geometry so that it doesn't have to duplicate work for every character afterwards. This is much more efficient, because all of the curve evaluation and nodes like fill curve don't have to repeat the same calculation for every instance of the same character. In the future, the instances component will support attributes, and the node can output attribute fields like "Word Index" and "Line Index".
