Support for the direct use of enums in the attributes of tags.

Assume there is the enum:

public enum LoginType {
  account, manager, reseller;
}

and a setter for a tag called 'page':

public void setLogin_required_type( LoginType login_required_type ) { ...

then the jsp code:

<ez:page login_required_type="account"/>

would result in the generation of the java code:

page_tag_instance.setLogin_required_type(LoginType.account);
