    Merge Bob Fewell's 'account-notes' into master.

commit 72bcf7f7afa4e00ea577535d049865bb5e172ebf

    Fix issue when editing the account tree view notes field
    
    When you try to edit a multiline account notes field in the account
    tree view you end up with just one line with control characters as it
    is being edited with a GtkCellRenderText cell. To fix this I have added
    a new cell renderer based on a text view.
