[Feature] Support Discord Development release

Is your feature request related to a problem? Please describe.

Bandaged BD does not support the Discord Development release:

Uncaught (in promise) TypeError: Cannot read property 'settings' of undefined
    at Object.getSettingGroup (remote.js:1)
    at Dt.initSettings (remote.js:1)
    at Dt.init (remote.js:1)
    at remote.js:1

Describe the feature you’d like

From a quick look at the codebase, it should be easy to support it. Here are some patches for master and development respectively:

Additional context

Here’s the download link for Linux.

The only differences should be the Electron version or native module versions iirc. Otherwise it runs off of Canary’s endpoints.

So a release channel that is barely used and is essentially a carbon copy of another channel?

Yep. Discord themselves say it’s discontinued which is kinda strange since they still update it separately from Canary.

Might add that it’s also available through windows and macOS. Just hidden behind an obscure api download link: https://discordapp.com/api/download/development?platform=win
