Add OAuth UI widgetry
Do not duplicate declarations with bidi-value()

Before these changes the following input:

    p {
        bidi-value(float, left, right);
    }

... would compile to the following output:

    p {
        float: left;
    }

    .html-rtl p {
        float: left;
        float: right;
    }

After these changes, the unnecessary "float: left" in the RTL version is
not included. This saves about 250 bytes of compiled CSS -- it's
something!
Revised nodejs v0.10.26 installation

* Install node.js v0.10.26 from a package stored in our Amazon S3 space

* Ensure the old version of node.js is removed

* Ensure any old installations of the fibers module are removed

* Add the rlwrap package

* Ensure the chris-lea node.js PPA is removed, because it no longer
  offers the exact node.js version we want

* Bonus: Only add the deadsnakes PPA when necessary

Bug 1002040: Expand the page-move error mail a bit more.

This adds the full traceback of the exception to the error, so that
less-easy things like character-encoding problems can be traced more
effectively.
