The general answer seems to be that all the more is an idiomatic way to say even more (http://en.wiktionary.org/wiki/all_the_more). Of course, that raises the question of the comparative -- even more than what? My sense is that in the phrase all the more, this is often (always?) left implied, and that all the more is really just an intensified version of more.
