Title: Ignoring namespaces for issue#17

Just ignoring namespace and backslahes in class names(wanted sgrep to work for files with namespaces), doesn't work correctly at all(i mean pretty-printer and others will just lose namespace keyword).

Also couldn`t figure out how to concat namespace names.

```ocaml
fully_qualified_class_name:
+ | backslashed_name { Name $1}

+backslashed_name:
+ | ident { $1 }
+ | T_BACKSLASH ident { $2 }
+ | backslashed_name T_BACKSLASH ident { $3 }
```
should be something like this
```ocaml
+ | backslashed_name T_BACKSLASH ident { Ast.rewrap_str
(Ast.info_to_str $1 ^ Ast.info_to_str $2 ^ Ast.info_to_str $3)
$1 }
```
But my ocaml-fu is not good enough to code it correctly.
