Add Controllable mixin

[jbaiter]

This adds a new Controllable mixin.

It allows blocks to specify custom UI elements that will be placed in the lower left corner of the block by default.
To do so, blocks will have to provide the following options:

controllable: true,
  controls: {
    'cmd-name': handlerFunction
}

To provide new icons for the custom UI elements, place a file cmd-name.svg into public/images/icons/src and re-generate the webfont via grunt webfont.

Example usage in my custom table block:

Really nice! I ended up moving the UI to the top right, and added buttons there, but yours is much nicer.

Sorry that we have't got back to this for such a long time. I think this would be a valuable addition to ST. It's relatively small code to add a really nice enhancement of ST's extensibility.

What do you think @cjbell88 and @andrewsprinz?
