	initExternalBlanks.js

	Checks all links in the current document, and sets the target attribute of any found that possess
	a "rel" attribute of "external" to "_blank".

	Note that this does *not* deal with forms - they will likely need something similar, but that 
	applies more directly to the base form object.
