~~~~~~~~~~~~~~~~~~~
* More blocks to customize the base template: `iommi_html_tag_attrs` and `iommi_html_tag_attrs`
* Added `Table.table_tag_wrapper` for when you want to wrap the `<table>` tag but not the paginator. This is useful for making apps work better on phone layouts.
* Insert the language code into the `<html>` tag.
* Generate deprecation warnings in all places not yet passing standard callback parameters
* Choices now passes correctly downstream from `Column(choices=...)` to the filter, the filters form, and bulk fields.
* The admin now can be inserted into the url patterns inside a named app (thanks Mickey McClellan)
