Pros of bubel over babel:
- No configuration (a la standard)
- Runs twice as fast, for quicker development
- Converts everything to ES5 (which is likely to be faster than ES6,
untested)
- Easy to swap Babel back in -- low commitment
Cons:
- Less battle-tested than Babel, but recommended by React core
developer so probably not too bad
- No babel plugin support, but we're not using that right now anyway.
Can switch back to babel if we need that later

Right now all Windows users are running a 32-bit app, even if their OS
is 64-bit.
Here's the plan to improve things:
1. We release a 64-bit installer, in addition to the 32-bit installer.
2. We auto-detect in the browser when a visitor is on a 32-bit vs.
64-bit OS and try to offer them the right installer. When in doubt, we
give them the 32-bit installer since that's safest.
3. The auto-updater will return the right binaries for the architecture
the user is on. This means that all our existing users who have 64-bit
OSs but are running the 32-bit app will get updated to the 64-bit app
on the next update. Also, 64-bit users who accidentally download the
32-bit installer will also get the 64-bit app on the next update.

Other notes:
- We don't generate 32-bit delta files. See reasoning inline.
- The package script now deletes extraneous Squirrel files (i.e.
*.nupkg delta files for older versions of the app) which should make
uploading the right files to GitHub easier. :)
The binary file naming works like this:
- Most users are on 64-bit systems, so they get nice clean file names
that don't specify an architecture (WebTorrentSetup-v1.0.0.exe). The
32-bit build files have the same naming but contain the string "-ia32"
at the end. In a few years, we will be able to just stop producing the
32-bit build files entirely.
- This means that the "WebTorrent-v0.15.0-linux-x64.zip" linux build
file is changing to "WebTorrent-v0.15.0-linux.zip" to match the Windows
naming convention. The .deb installer files must contain to
architecture in order to install correctly, so those do not change.
- Mac is 100% 64-bit, so it does not change.
