/********************************************************************** 
Função de formatação de campos do tipo Data 

Objetivos : 
    - Mascarar a entrada de dados no formato : dd/mm/aaaa 

Parâmetros : 
    objeto        -> Nome do campo de formulário (Usar this) 
    teclapress    -> Tecla pressionada (Usar event) 

Exemplo : 
    OnKeyDown    FormataData(this,event); 

Requirido : 
    Função ValidaData
