Similar to the profile form, the login form now parses and validates itself, with the InputField structs that the templates expect. I realized that i was doing more work than necessary when parsing fields fro the profile form because i was repeating the operation and the field name, so now it is a function of InputField. This time i needed extra attributes for the login form. I am not sure that the Go source code needs to know about HTML attributes, but it was the easiest way to pass them to the template.
