Merge branch 'note-form-buttons' into 'master'

Note form

A lot of the forms have the same actions associated with them so I have created a standard class that encapsulate these actions.

There is also another class that allows toolbar action buttons to be added that will insert different characters based on the HTML `data-prefix` attribute value - this will give us the opportunity to add more actions to the form and maybe create a markdown toolbar in the future.

See merge request !3534
