This makes it a bit more useful, as the user doesn't have to explicitly
ask for completion, it just provides completions, and tries really hard
to avoid suggesting things where they're not expected, for instance:
(cursor positions denoted as pipes)
```
@G | {|
foo: bar |
foo |
}
```
The user does not expect any suggestions in any of those cursor positions,
so provide no suggestions for such cases. This prevents the automatic autocomplete
getting in the way of the user, esp. when they try to press return fully
expecting to go to a new line.
The text editor is now populated with some very basic GML after startup:
@GUI::Widget {
layout: @GUI::VerticalBoxLayout {
}
// Now add some widgets!
}
Less typing, less intimidating! :^)
