[photran-dev] Some packages renamed/classes moved

[Jeffrey Overbey <subscribe-photran-dev@xxxxxxxxxxxx>]

Since Photran's 5.0 release is coming up at the end of the month, I had 
to add "internal" to some package names to make it clear that they are 
not part of any published API.

If you have local changes and updating from CVS breaks your code, just 
click Source > Organize Imports.  No classes have changed; they're 
probably just in a package with a different name.
