[OPEN-EXTJSIV-207] Mixins issues

[LesJ]

See this code fragment in Ed's blog:

http://edspencer.net/2011/01/classes...-the-hood.html

//it’s easy to add more later too
MyClass.mixin('draggable', 'Ext.util.Draggable');

I see that the mixin() method is marked as private in Base.js. Should it be public?

Second issue:

I see that the Component class is using the 'Ext.util.Floating' mixin, but by default the floating config is set to false.

Should 'Ext.util.Floating' be mixed in only if floating is true?

[Sakuro]

I think Base.mixin should be public, as Base.override is.

Also, there are some references in blog posts to the Ext.util.Draggable mixin, but I see no reference within the API docs. Is this an oversight?

The docs should reference class mixins, we'll look into why this may not be happening.
