Decode HTML Template Tag

This is useful if you have a string that is html encoded (i.e. "&lt;p&gt;Hello world!&lt;/p&gt;") and you want to do something more complex than just display it as html, such as using the striptags filter.

Horizontal RadioSelect widget

The problem with Django's default Radio button widget is that it puts the buttons in a vertical format and the documentation is somewhat silent on how to make them horizontal. If you are dealing with a long list of buttons then veritical is probably the way to go but if you are dealing with "YES/NO" situation or any other boolean choice then you will probably want them horizontal. Basically I just took the code and even the explanation from here: https://wikis.utexas.edu/display/~bm6432/Django-Modifying+RadioSelect+Widget+to+have+horizontal+buttons

Coalesce for F()

Updating fields that allow for NULLs must take care about those NULLs. Use case: `Message.objects.filter(id=1).update(price=CF('price', 0) + 7)` `Message.objects.filter(id=1).update(status=CF('status') // 's')` Works for postgres. Supposedly works for mysql. Didn't test with other backends.

True Unique Boolean Decorator

Useful when you want to keep only one instance of a model to be the default one. This is a decorative way of doing the same as in http://djangosnippets.org/snippets/1830/ Can this be made better as a class decorator (not having to declare explicitly the save method) ?
