New Feature: mixer add-bundles about mixer-tools

In addition to that, it may be nice to also have a "list-bundles" command, that fetches and displays the available bundles for the clear version you are using.

@rchiossi -- I could see that potentially being useful, but I would see that as a separate command altogether.

The "add-bundles" command moves further in the direction of abstracting away the offline bundle cache (i.e., the user doesn't need to know where it lives or that it even exists in order to add bundles), and so I can see your proposal as a useful addition to that direction. Of course, there are well over 100 bundles in most versions of CLR, so the output would likely only be useful in conjunction with grep/less.

@mdhorn pointed out that if this is intended to be "the" way you add bundles from CLR to your mix, it really should support an --all flag, so I just submitted a PR (#36) to implement this.
