No lpi, so no compiler options and no packages.

There is already a single file feature under Run / Configure Build+Run file. At
the moment Run simply executes it. It does not use the debugger.
The compiler options and run parameters are saved as IDE directives in the
source.
You can have an arbirary number of such single file programs and they are
compiled and run with the shortcuts.
Of course there is room for improvements. For example the project has higher
precedence. For students a special project might be needed that favors single
file programs.
