The accessibility modifiers (as specified in Robert's recent e-mails) will be "public", "package", "protected",
"public-readable", and "non-writable". "private" will go away. The default accessibility is "private to the current
script". Status: partially implemented, currently we implement "readable" instead of "public-readable".
The code completion must be checked to suggest proper keywords.
This revision should check in the basic support for the access modifiers.
The rest will be bugs.
