feat(core): renames Property into Input and Event into Output

BREACKING CHANGE:

Before: @Directive({properties: ['one'], events: ['two']})
After: @Directive({inputs: ['one'], outputs: ['two']})

Before: @Component({properties: ['one'], events: ['two']})
After: @Componet({inputs: ['one'], outputs: ['two']})

Before: class A {@Property() one; @Event() two;}
After: class A {@Input() one; @Output() two;}
