Loading dojox.analytics.Urchin before dojox.analytics doesn't work

[guest]

If you load in dojox.analytics.Urchin and then dojox.analytics then Urchin is no longer available because in dojox.analytics._base it has the following:

dojox.analytics = { ... };

Suggested fix is to use mixin instead:

dojo.mixin(dojox.analytics, { ... });

(In [14273]) make sure base is loaded before urchin for analyitics. fixes #7074

(In [14281]) refs #7074 - Urchin doesn't use/need anything from dojox.analytics except the namespace, which _base destroys. Requiring _base before Urchin fixes the problem. No need to always include _base code in Urchin -- it is simply unnecessary code. Documenting the extremly unlikly usecase where a user would want Urchin AND local tracking, and keeping Urchin small + dependency free
