This commit add $.create(), which allows you to create a
jQuery object that just has a name to identify it, as opposed
to some selector or HTML fragment. It's useful for things that
are really used as stubs.
This also fixes a bunch of the existing tests to use $.create().
Before this fix, you could actually just do $('some-stub'), but
now we enforce that the input to $() looks like a valid selector
or HTML fragment, and we make some exceptions for things like
window-stub and document-stub.
Hopefully this will make it more explicit that zjquery does
not truly simulate DOM, but it instead allows you to dynamically
set what you want the results of $('foo').find(some_selector)
to be.
Before this commit, we were erroneously setting up parents
as part of add_child() calls, but it's not necessarily the
case that those children are immediate children, and therefore
the first object is not necessarily the immediate parent.
