Show line numbers in "split" examples

With the commands like `\skip`, `\skipline` it is possible to show parts of a file for further explanation / tutorials. They can be started with `\include` or `\dontinclude` but in case `\include` specifies that the line numbers have to be shown they are only shown in the full example and not in the split up example
- show line numbers in split up example in case `lineno` is required
- add `lineno` option to `\dontinclude` so here also line numbers can be shown.
