login form.
Made a method that returns the element with the given name, which makes
some other methods shorter.
Don't pass hidden elements to the form element renderer, they're not
needed. Although some thought might need to go into how exactly they will
be placed later.

slurping cancel requests from other forms.

checking (maybe this should go in setup, we're always going to want it

next/prev checking

sensible defaults :)

name anyway, added a @todo

to be discussed (whether invalid cronjobs should cause the whole plugin
to not install)

and fixed up references to Auth_* classes.

does postinst and stuff

(cron/postinst/events). fixed a few todos too.

get the style attributes out of the form renderer and still see if the HTML
worked.

anyway, but who cares, it's for testing :)

    (currently there's only a <div> renderer but in future there will probably
    be a <table> renderer, and possibly a <ul> one too).
  * Get information about the form values from the correct superglobal.
  * Moved rules into their own array in the form definition array.
  * Added a method that retrieves the error on a form element if there is
    one.

stuff no longer needed.
