Lost Textarea component after issue #59

The componente Textarea was replaced to input with multiline attribute, but for this is not a good solution because this broken all applications was using Textarea component.
#59

In my opinion in this moment when de library is very new, its not a very big problem, but if I has multiple applications using unform and components has removed because other people resolve remove in new feacture, surely I would decide to stop using unform.

My suggestion is maintenance TextArea component and this component call the input with multiline param.

Concept bug, is not a functional bug at moment.
