v0.12.3

Features

• Filters are now inherited (e.g. Email and Uri work like String because they inherits from it)
• Added filters for DateString, DateTimeString (Thanks, @boydgreenfield)
• Implemented ItemUri.convert(). This means you can now specify filters for the "$uri" field. For more info, see below. (Thanks, @boydgreenfield)

Bugfixes

• Fixes specifying custom filters using Meta.filters

---

Enabling filtering by "$uri" in a resource:

        class Meta:
            filters = {
                '$uri': {
                    None: filters.EqualFilter,
                    'eq': filters.EqualFilter,
                    'ne': filters.NotEqualFilter,
                    'in': filters.InFilter
                },
                '*': True
            }

Note that filters needs to correspond to the manager implementation you are using, e.g. flask_potion.contrib.alchemy.filters. If you want to enable the filter in multiple resources, you can use a Meta mixin.
