Analogue template filter to removetags that also removes the content of the tag
Django's builtin `removetags` filter removes the supplied tags, but leaves the enclosed text alone. Sometimes you need the complete tag, including its content to go away. Example: <h1>Some headline</h1> <p>Some text</p> Applying `removetags:"h1"` to this html results in Some headline <p>Some text</p> while `killtags:"h1"` leaves <p>Some text</p>

Sane OneToOne getter
Since django insists on throwing a DoesNotExist rather than just returning a None from the far side of a null OneToOneField, I wrote this to have a sane way of getting those fields out without having to try/except all over in my code.

- OneToOneField

New view decorator to only cache pages for anonymous users
This is an addition to Django's cache_page decorator. I wanted to cache pages for anonymous users but not cache the same page for logged in users. There's middleware to do this at a site-wide level, and it also gives you the ability to partition anonymous users, but then you have to tell Django which pages not to cache with @never_cache.

RelatedNullFilterSpec: django-admin custom filter all/null/not null/choices
A simple django-admin filter to replace standar RelatedFilterSpec with one with the "All"/"Null"/"Not null" options. It applies to all relational fields (ForeignKey, ManyToManyField). You can put the code in the `__init__.py` or wherever you want. The `_register_front` idea is copied on [this snippet](http://djangosnippets.org/snippets/1963/)

- admin
- null
- filterspec
- ManyToManyField
- ForeignKey

A RegexpField that clean the regex match using the desired format
I wanted a way to allow flexible phone number validation while making sure the saved data was uniform. ex. With: RegexFormatField(r'^\(?(?P<area>\d{3})\)?[-\s.]?(?P<local>\d{3})[-\s.]?(?P<subscriber>\d{4})$', format='%(area)s %(local)s-%(subscriber)s') input: (444) 444-4444 444 444-4444 444-444-4444 444.444.4444 4444444444 output: 444 444-4444
