The parser written in Slate is beginning to work!

[Paul Dufresne]

After changing parser findVariable: to parser currentScope findVariable, I 
am beginning to be
able to parse stuff! I include session log here:

Please answer with y or n :

Maybe there would be a need for an empty root currentScope?

Anyway, that's an interesting beginning I wanted to share.

And fixing the FileStream problem, will allows us to test the parser with 
real files...
