Space indentation in features

[fernandoacorreia]

Support feature files indented with spaces instead of tabs.

If we take a working feature file and convert all tabs into a number of spaces, cucumis outputs this error message:

message: Unexpected token "SENTENCE" at line 1

I would like to see this implemented too. Developer IDEs are regularly configured to indent with spaces (i.e. use spaces for tabs) because tabs are often rendered with varying lengths on different viewers which can break indentation in particular when developers mix tabs and spaces. It is possible to workaround this but would be nice not to have to.

At minimum there should be a more informative error message that explains the need for tabs rather than spaces for indentation.
