Filter to resize a ImageField on demand

A filter to resize a ImageField on demand, a use case could be: ` <img src="object.get_image_url" alt="original image"> <img src="object.image|thumbnail" alt="image resized to default 200x200 format"> <img src="object.image|thumbnail:"200x300" alt="image resized to 200x300"> ` The filter is applied to a image field (not the image url get from *get_image_url* method of the model), supposing the image filename is "image.jpg", it checks if there is a file called "image_200x200.jpg" or "image_200x300.jpg" on the second case, if the file isn't there, it resizes the original image, finally it returns the proper url to the resized image. There is a **TODO**: the filter isn't checking if the original filename is newer than the cached resized image, it should check it and resize the image again in this case.
