itools.csv
================

(1) Remove the 'row_class' variable, don't allow anymore to override it.

(2) Replace class variable 'skip_header' by 'has_header':

  # Before
  skip_header = True

  # Now
  has_header = True


itools.database
================

(1) Rename class variable to define whether unknown fields are allowed or
not:

  # Before
  class_schema_extensible = True

  # Now
  fields_soft = True


itools.web
================

(1) Now views are prototypes, so:

  # Before
  @property
  def foo(self):

  # Now
  @proto_property
  def foo(self):


(2) The STLForm class has been merged into STLView:

  # Before
  from itools.web import STLForm
  class MyView(STLForm):

  # Now
  from itools.web import STLView
  class MyView(STLView):

(3) The resources 'get_abspath' method has been removed, use 'abspath'
instead:

  # Before
  resource.get_abspath()

  # Now
  resource.abspath
