Merge lp:~bjornt/lazr-js/prefetch-yui-3.5 into lp:lazr-js

[Björn Tillenius]

Don't reference the script function directly, so that it can access the
YUI object as 'this'.

In YUI 3.5 the script function is changed, so that it calls
this._load(). If we assign the script function to a variable, this won't
get bound to the YUI object.

This change is backward-compatible, so this code works with older
versions of YUI as well.
