[Fixed]-Django-taggit tags with whitespace in name?

Multi-word tags in Wagtail need to be quoted, e.g. “my tag”.

There are two pull requests open that address this topic:

• https://github.com/torchbox/wagtail/issues/1874 to improve documentation and explain users that at the moment multi-word tags need to be quoted
• https://github.com/torchbox/wagtail/pull/2207 to allow multi-word tags written with spaces
