parameter name of Deferred constructor can be more semantic

parameter name of Deferred constructor can be more semantic

Currently the jQuery define Deferred as

Deferred: function ( func ),

I suggest it can be defined as

Deferred: function ( initialize )

or

Deferred: function ( initializeFn )

or

Deferred: function ( initializer )

so that the semantics is more explicit, and code is more self-documented.
