Support only-of-type pseudo-class selector

[GoogleCodeExporter]

What new or enhanced feature are you proposing?

Represents an element that has a parent element and whose parent element
has no other element children with the same expanded element name. Same as
:first-of-type:last-of-type or :nth-of-type(1):nth-last-of-type(1), but
with a lower specificity.

What goal would this enhancement help you achieve?

Greater CSS Selectors Level 3 compliance.
