Refactored Rendering of the fields. Added a new class "Field" to the form
module. This new class is a wrapper for the form config comming from the
configuration and the FA field. It provides a common interface to the
Renderer, which make handling of field attributes in the renderer more easy.
Added helper function to read the formbar css

Moved css into a subfolder. Added a function to read it from there and return
the content.
Added hardlink to the formbar css file
Do not reset the field to readonly

At this point the field should already be readonly. The setting has aready be
done during the field setup method in the fahelpers modul.
Set datatype of password fields to password
Change Renderer depending on the datatype.

Added some functions in the fahelpers module to set the Renderer based on the
datatype comming from the configuration.
Added error handling in validator for FA relations

For 1:1 relations FormAlchemy modifies the fieldname of the rendered field the
the name of the Foreignkey which is references another object. This causes
problems in the current validation code. First solution is now to just log the
warning for this case, skip any validation and store the raw submitted value
into the data dictionary.
Fixed logic on initialization of fields.
Fixed tests on unknown fields.
Added readonly flag to forms.
Provide readonly flag from config when configuring the field.
Set readonly flag in customform.
Propagate the readonly flag of form to the field

If the readonly flag is set for the form set all included field readonly too.
Adapted and added testcases.
Reverted former change on configuring fields

Do not provide the readonly flag of the form to the configured_fields method. The field is already configured as readonly at this point. Already done in the configuration.
Fixed prefilling of values in render form.

the htmlfill render method is only used in case the user provides values to be prefilled
Fixed height of some elements.
Fixed height and alignment of readonlyfields.

Setting height to 32px seems not to work when adding some padding to the
element. So remove the height.
Changed rendering of the field
