Pass autocompleteBraces setting to source editor

Reads the autocompleteBraces setting via @appsettings and passes it to the
SourceEditorConfiguration's behavior, enabling the setting to actually control
whether brackets are auto-completed in the editor.

Requires corresponding change in CodeEditSourceEditor.

Fixes #1691
