The major enhancement this release is that the entire Traits package has been
changed to use relative imports so that it can be installed as a sub-package
inside another larger library or package. This was not previously possible,
since the various modules inside Traits would import each other directly
through "traits.[module]". Many thanks to Darren Dale for the
patch.

There have been numerous minor bugfixes since the last release. The most notable
ones are:

* Many fixes involve making Traits UI more robust if wxPython is not installed
on a system. In the past, we have been able to use Qt if it was also
installed, but removing Wx would lead to a variety of little bugs in various
places. We've squashed a number of these. We've also added better checks
to make sure we're selecting the right toolkit at import and at runtime.

* A nasty cyclic reference was discovered and eliminated in DelegatesTo traits.

* The Undefined and Uninitialized Traits were made into true singletons.

* Much of the inconsistent formatting across the entire Traits source has
been eliminated and normalized (tabs/spaces, line endings).
