Adds more events to Matrix fields and the Entry Type switcher

[joshangell]

Craft.MatrixInput gets afterInit which fires at the very end of the init method, and blockAdded which fires just after a new block has been added to the DOM.

The blockAdded event also provides the new block html via the event.data property e.g.:

Garnish.on(Craft.MatrixInput, 'afterInit', function(ev){
    var $newBlock = $(ev.data.block);
    // ...
});

Craft.EntryTypeSwitcher gets beforeTypeChange which fires just before any changes to the DOM are made.
