Formish

----

BUGFIX: The request_data was not being set on the form as a dotted_dict post
0.8, hence deep sequences were not working correctly

-----

API CHANGES:

* Action init argument changes and add_action argument changes. Also, a
default form now has an action in form.actions

A form now has a 'add_default_action' keyword argument that defaults to True.
Action init now takes (name, value=None, callback=None).
The default action on a form has a value of 'Submit' and a name of 'submit'.
You can manage the list of actions explicitly. A value of None removes the
value html attribute.

css_class correctly and not nesting html ul/li's correctly

------

* Input widgets can be used for sequence data (csv input field)
* Added support for GET forms
* Included css template in main formish module
* Made success/failure form callback more flexible and intuitive
* Reviewed use of css class and id names and added prefixes to field, widget
and type to prevent clashes

* Better reprs for widgets and form definitions
* Documentation improvements
- Started adding doctests to documentation
- Reduced the weight of the documentation (simplify styling/templates)
* Lots of changes to the way file uploads are handled - will document before a
tagged release
- Using a 'headered' filestore that allows meta information to be stored
with the file
- this means cached files are not browseable on the filesystem anymore
- fixed bugs in thumbnail preview
- lots more tests around cacheing and file store

BUG FIX: There were some errors in the previous file upload system but the
replacement of the file upload system has improved the whole file
upload system
