Display timestamps in the user's local timezone.

Previously the timestamps were left untranslated from UTC.  The result of this was that timestamps appeared to be wrong for a user in a non-UTC/GMT timezone even if the server was in the same timezone as the user.

Fixes #121 and #139.
Prevent stack overflow if adapted command calls own methods.

This changes the adapter to aggregate the adapted command rather than inheriting from it because the latter can lead to a stack overflow if the superclass calls the adapted method in its implementation.  In other words, the adapter method would delegate to a method of the inner which, via virtual method dispatch, ends up delegating back the the adapter method.
