MDL-44711 course: fixed navigation expansion in course tests
Automatically generated installer lang files
MDL-45536 atto_html: Update the textarea size when switching to HTML view
MDL-45239 editor_atto: On Android do not restore focus in the callbackWrapper

It seems that Android automatically focuses the cursor in the last position
when the content editable region is programatically re-focused.

Whilst this does not cause an issue on it's own, when combined with the
behaviour of the dictionary auto-completion to restore focus on the start
of the word when a word has not yet been finished, this was causing us to
change focus when pressing buttons.
