[FEATURE] Convert Spaces into hyphens (or slug)

[surjithctly]

Hey,

Awesome plugin.

When I add tags with a space character, eg: My Tag, it's adding it as the same string. However, while using the tags on a real project and if I wanted to filter by tags, I will use ?tags=My Tag, the browser will convert it to ?tags=My%20Tags

To avoid that, it would be great to add an option[ slugify: true ] to convert the text to a lowercase hyphened string. eg: my-tag, then it would be great.
