Add more flexibility by not decorating default controller

[mpoiriert]

This will allow to override the create method even if we are using another controller for the admin.

Also the decorates is not implemented properly since you must call all the methods of the original decorated controller (the MediaAdminController does override the listAction).

It's better to not decorate in this case.

We could also consider renaming the controller MediaAdminController for CreateController to follow naming convetion of "MultiUploadController"

@mpoiriert have you tested it?

[mpoiriert]

@silasjoisten I have rename the controller.

I did also change the MultiUploadController to rely on "$this->admin" instead of injecting the MediaAdmin. This remove code and allow to have a custom Media Admin instead of forcing use to use the provided MediaAdmin.

I have use my branch directly in my project so I do confirm it's working.
