Add parameter name reflection

[tipsy]

Allows for writing attribute-names as lambda-params:

link().withAttrs(rel-> "stylesheet", href -> "/styles.css");

form().withAttrs(method -> "post", action -> "/form-path").with(
    input().withAttrs(name -> "email", type -> "email"),
    input().withAttrs(name -> "password", type -> "password")
);
