Title: Recognize `+<mixin>` mixins as tags

This change allows the `+()` syntax to be highlighted the same as tags. (Example: `+item(name="test")`.) This highlights the attributes and nested tags (e.g. `+item(name="foo"): p bar`). For documentation on these mixins, see https://github.com/visionmedia/jade/blob/master/jade.md.

I just changed the tag syntax to allow a `+` before the tag name. Not sure if this is the best way to get this accomplished or not.
