[SVN] r3314 (Io)

[Rob Rix]

- scope self, sender, etc as variable.language.io by analogy with the ObjC language's handling of "self" (note that this is not consistent with C++'s handling of "this" but there may be some subtle difference which eludes me)
- repair the () and ,) meta-scopes to match the new behaviour of applying scope to the left instead of to the right
