29804	Add 'Did you mean' suggestions for unsupported lookup error	Rich Jones	Abhinav Patil	"I often find myself running into `django.core.exceptions.FieldError: Unsupported lookup 'is_null' for DateTimeField or join on the field not permitted.` - and it seems like plenty of other people on StackOverflow do as well.

It'd be great if we hit an unsupported lookup, we could suggest the correct one if if it's similar, so it'd become:

`django.core.exceptions.FieldError: Unsupported lookup 'is_null' for DateTimeField or join on the field not permitted - did you mean isnull?`
