Fixed #5546: split form unit tests into manageable chunks. This isn't a perfect fix since the chunks aren't yet autodiscovered, but that shouldn't prevent checking this in. Thanks, Leo Soto. git-svn-id: http://code.djangoproject.com/svn/django/trunk@6379 bcc190cf-cafb-0310-a4f2-bffc1f526a37

# Fields #
##########
Each Field class does some sort of validation. Each Field has a clean() method,
which either raises django.newforms.ValidationError or returns the "clean"
data -- usually a Unicode object, but, in some rare cases, a list.
Each Field's __init__() takes at least these parameters:
required -- Boolean that specifies whether the field is required.
True by default.
widget -- A Widget class, or instance of a Widget class, that should be
used for this Field when displaying it. Each Field has a default
Widget that it'll use if you don't specify this. In most cases,
the default widget is TextInput.
label -- A verbose name for this field, for use in displaying this field in
a form. By default, Django will use a "pretty" version of the form
field name, if the Field is part of a Form.
initial -- A value to use in this Field's initial display. This value is
*not* used as a fallback if data isn't given.
Other than that, the Field subclasses have class-specific options for
__init__(). For example, CharField has a max_length option.
