This implements an SDK.Scanner which handles any given
adapters and manages the scans. This change enables continuous
scanning without the need to `.scan()` scheduling in other places.

* refactor(SDK): make adaptor scan functions event based
This change will allow us to start emitting progress events out of the
adaptors scan functions.

* refactor(sdk): Make adapters event emitters
This commit installs `node-usb` v1.3.0 from GitHub, since that version
was never published to NPM, and is the only one that works with Visual
Studio 2015 (see https://github.com/tessel/node-usb/issues/109).
The usbboot communicates with a Raspberry Pi / Amber through USB and
eventually mounts it as a block device we can write to.
This feature bundles bootcode.bin and start.elf from the original
usbboot implementation.
The flow is the following:
- On each scan, the usbboot scanner will try to get a usbboot compatible
USB device to the next "phase", until they are all transformed to
block devices the user can flash to as usual

This is a major first step towards adopting an SDK architecture. This
commit creates an SDK adaptor with a `.scan()` function that uses
`drivelist` under the hood. Then, an SDK orchestrator is used to provide
drive scanning capabilities to the GUI.
Here's a list of some particularly interesting changes:
- The drives returned by the SDK adaptor now have a "pending" and an
"adaptor" property. The "pending" property is a boolean flag that
determines if the drive is ready to be used (this will come handy for
usbboot), while the "adaptor" property simply contains the name of the
adaptor that drive came from
- The GUI drive scanner Rx implementation was replaces with a "promise
loop." Before, the drive scanning routine would be called every 2
seconds (without waiting for the previous scan to complete), while
now, the next scan happens *after* the previous scan completes. For
this reason, I reduced the drive scanning interval timeout to match
the timing we had before
