In case createElements() would still return the elements while requiring
the caller to add them to the form all form dependent configurations get
lost. (displaygroups, belongTo, ...) Wizards or parent forms can still
retrieve only input relevant fields by just calling createElements() and
getElements().

Replaced `ElementWrapper' and `HelpText' with Zend's `HtmlTag' and `Label' respectively.
Instances of Zend_Form_Element returned by `Form::createElements()' now receive our desired default decorators.
refs #5525
`Form::getName()' auto-detects the form's name if it's not set and sets the form's name using `Zend_Form::setName()'.
`Zend_Form::setName()' then filters the form name stripping backslash '\' characters. The first call to `Form::getName()'
did not regard the filtering and thus returned the unfiltered name which led to `Form::wasSent()' returning `false'.

This allows us to write generic forms like the ConfirmRemoval form but to
utilize handleRequest() while providing a closure in the array that is passed
to a form's constructor.

We require forms to set autosubmit=true on elements which are supposed
to be submitted automatically now. The base form then ensures that this
works in JS environments and non-JS environments as well by applying the
right changes to the HTML.
refs #5525
There is currently no usecase for onFailure() but for onShow() wherewith
the case is covered when a form needs to be prepared before showing it
to the user while the form was not submitted in any way.
refs #5525
This way concrete form implementations can also simply fetch form
dependent request values without referring to the form's submission
method.
refs #5525
How forms are being validated should not be a task that is part of the
controller action, but should be handled by the form base class as it is
most of the time the same procedure. Now a controller action just sets
up the form to use, calls handleRequest() and acts upon its return value.
(e.g. calling handleRequest() from another form or any redirection)

It is not sufficient to just check whether all required elements are being
submitted. We definetely need to check whether the submit button was
pressed. But doing this and providing a standard button with a static name
simultaneously will produce conflicts if forms are using the same action
urls. To fix this, we'll add an additional form-identification check by using
a form's name or class.
refs #5525
Setting an url with parameters named like form elements in a form with
method POST causes Zend to ignore any POST data because GET will be
processed with higher priority.

Since we are using mainly createElement and addElement is only an alias for
createElement if no object is passed our changes to addElement can safely
be moved to createElement.
refs #5525
Form creation must not depend on specific function calls. If a forms' elements are required and missing, create them. Form::isValid() must be
able to determine whether a form can be processed or not without to rely
on a particular button value.
