New feature: selfOrParents traversal function

[jollytoad]

I find it handy to be able to traverse using parents, but include the current context in the search, like the XPath ancestors-or-self axis.

It's very handy for this kind of thing:

if (!$(...).selfOrParents(':hidden').length) {

do something because we are visible

}

rather than having to do:

var tmp = $(...);

if (!(tmp.is(':hidden')

tmp.parents(':hidden').length)) { ... }

I've attached a patch, it's very small :)

If I'm not wrong, that can be achieved with:

$(...).parents().andSelf().is(':hidden')

That seems to me like pretty much the same amount of code. So.. I think this is not really useful, generally speaking.
