Public instance Xtext editor requires sendFullText

[barnettwilliam]

The current deployment of the public instance on the King's CREATE cloud requires sendFullText to be set to true so the ace editor is working in stateless mode. It appears to be the Xtext service session cookie is not being set/forwarded so the remote editor contents cannot be modified.

The Xtext editor is initialised here:

educationplatform/platform/src/XtextEditorPanel.js

Line 22 in cfe2cbf

aceEditor = xtext.createEditor({

Adding this to to the init object species stateless mode

sendFullText: true

In the long term we may want to consider moving to LSP based editors for more general support of other languages.
