Fixing #3

Well, well, well...

I dig up so much, it turn out our problem was due to a bug in Symphony!

Remember when I said in issue #3

> Keys are there, but not the value...

Turns our this was the problem. So I fixed it, and everything came back to life ! Yé !

See the fix: https://github.com/DeuxHuitHuit/symphony-2/commit/d571c45dba053f8faa3a14feb2aaa7973a621ce8 So simple !!!

EDIT: I change a couple of other neat things and fixed a bug when the override option is off. Hope you like it !

BTW, sorry I did not took the time to create a new branch... I can rebase if you have problems with the PR.
