Sprox 0.8.3 released

[Alessandro Molina]

I'm pleased to announce that Sprox 0.8.3 has just been released on PyPi.

This is mostly a bugfix release but includes also support to implement substring searches in Table fillers and orm providers. This enables to filter for entries that contain a piece of text instead of exactly having the specified text.

The following changes are included in the release:

* Support for default values in MongoDB

* Support for callables as default values for form fields

* Support for substring searches in FillerBase filters through the substring_filters

list of fields to search for substrings instead of comparing for equality

* Fix MongoDB is_binary

* Fix MongoDB Checkboxes

* Fix requiring column defaults requiring __nonzero__

* Fix SQLA relation with lazy='dynamic' in FillerBase, make tables able to show

entries for dynamic relations

* Improve Validator Selection for DateTime, fixes issues with dates on TW2
