Merge branch '1-substituir-dependencias-diretas-por-modulos-de-di' into 'master'

Dependências diretas substituídas por módulos de DI.

Dependency Injection incluída usando Dagger, com módulos (ApplicationModule e ActivityModule) e componentes (ApplicationComponent e ActivityComponent) criados. Todas as dependências diretas, presentes nas Views (Login, Main e Splash), na classe MvpApp e no DataManager foram substituídas pelos módulos de DI.
Closes #1
