[imp-dev] LanguageActionsContributor stuff needs committing

["Jurgen Vinju" <Jurgen.Vinju@xxxxxx>]

Hi guys,

I'm dying to commit my code to imp.runtime. Can I do that today?
People here really want to use the new features.

Remember, after the commit all implementations of
ILanguageActionContributor will break in a small way, they can be
fixed by changing:
  "implements ILanguageActionContributor" to "extends
DefaultLanguageActionContributor".

Cheers,

Jurgen
