Making it easier to import projects into eclipse

I am pull requesting those changes in order to make importing projects into eclipse from the command-line easier. 
I have tested it with Kepler ScalaIDE. 
The idea is simple: one should be able to import eclipse projects with just an eclipse:eclipse command. 



Entiendo que esto pisa a lo que definiste en el general... pero no debería ir algún tipo de información sobre el XText nature?
