discord: 0.0.13 -> 0.0.1

Despite the version number confusion, this is a new version of
discord-canary, but since the build is now public/official, the version
number has been reset and the canary suffix has been dropped.

Note that this means that the executable has been renamed from
DiscordCanary to Discord
