manual: added documentation about replacement of 'untitled.ext' with filename (#1804)

On "Save As..." a text in the form 'untitled.ext' will be replaced with the chosen
filename if it is found in the first 3 lines of the document. This PR adds a description
of the feature to the manual. Fixes #753.

+Automatic filename insertion on `Save As...`
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+If a document is saved via `Document->Save As...` then the filename is
+automatically inserted into the comment header replacing text like
+`untitled.ext` in the first 3 lines of the file. E.g. if a new ``.c``
+file is created using `File->New (with Template)` then the text `untitled.c`
+in line 2 would be replaced with the choosen file name on `Save As...`
+(this example assumes the default file templates being used).
