Updates AMMM to the latest versions of Flocking and Infusion

This pull request updates:

1. To the latest version of Flocking's master branch
2. To the latest Infusion 1.5 snapshot (unminified and renamed to infusion-framework.js)
3. The build scripts, including minification of Infusion
4. The Arpeggiator, to fix one API-breaking change in the latest version of Flocking

I have tested this with all the demos in the master branch but was unable to test the distribution branch because it doesn't seem to have any lineage with master. If you describe how to update it, I can. 

At some point, perhaps it makes sense to modify the distribution branch so it is directly related to master in some way?
