Download GitHub Desktop Plus 3.5.7-r2

Upstream: GitHub Desktop 3.5.7-beta3 release notes
Changes and improvements:
- We now support multiple app windows! To use them, either select File > Open new window, use the keyboard shortcut Ctrl+Alt+N (Cmd+Option+N on macOS), or right-click on a repository in the repo list and select Open repository in new window. Thank you @hewigovens!
- Allow users to hide the "Compare" tab in the commit list.
While I wouldn't recommend hiding it, if all your repositories have a single branch or you just never use this feature, you can now remove it in File > Options > Appearance.
Fixes:
- Fixed a crash when attempting to add a repository with an SSH remote URL that doesn't start with git@. Thank you @coocoo1112!
- Fixed a problem in the welcome flow where the text in the Enterprise URL textbox appeared reversed. Thank you @coocoo1112!
- Fixed the infamous "cannot read property 'path' of undefined" error when launching the terminal (Ctrl+`) without configuring a terminal first.
