Add TextDocument with full size editor

A new document object App::TextDocument. It has a property Text which holds the text of the document as a string. This commit also contains a full size editor based on QPlainTextEdit. It can only be used by the TextDocument and has a read only mode invoked for read only documents (ReadOnly property set to true). The editor is invoked by a double click on the TextDocument.
