The fact that this comes from a command line is a detail outside the scope of
this class. The method should be called something like AddOverride(), and the
comment should explain that it will override any previously registered component
extension with the same ID.

Nit: it looks like "extensions" fits on the previous line.

Since now comment for the prev method reflects this one as well the comment
removed.

Comment is incorrect, nothing is unloaded here.

Fixed.

Nit: capitalize "ID".

[SeRya, 2011/11/29 21:31:00]

It is 'Id' everywhere except a few unit tests. Including Extension::GenerateId.
