Description

I am using django-oscar , which has a bunch of failures across its many constituted apps, including the following three views

'dashboard:catalogue-attribute-option-group-create',
'dashboard:catalogue-class-create',
'dashboard:catalogue-product-create',

However, I need to omit the namespace when I put them into SKIP_SMOKE_TESTS.
i.e.

'catalogue-attribute-option-group-create',
'catalogue-class-create',
'catalogue-product-create',

There are others like 'customer:order' which need to become 'order'.
I am sure that I will have a few cases of view names which need a namespace in order to be distinct, but I guess the skip would apply to all with the same name, so that outcome isnt terrible.

However more importantly, it took me a while to recognise that the namespace needed to be omitted. A quick README update would be helpful, if a proper solution isnt easy.

Related to #17.

It has been fixed in v2.0.0. Thanks @jayvdb!
