Summary:
This adds support for flipper logs in Sandy, including some theme adjustments.
Did remove storage and showing of debug messages, as I noticed it tends to crash Flipper after a while since there are so many. Also added a fixed limit of only remembering last 1000
Also converted Toolbar and button with dropdown items to Sandy.

Summary:
Handling issues typically start with: did you look at the Electron logs? Since Flipper is such an extensible tool, running in varying environments I think the console should be support as first class concept. Many errors are currently not shown to the user. This PR is a first attempt to fix that.
The implementation is based on https://github.com/samdenty/console-feed, which is used by quite some web based IDE like tools (like codesandbox), and offers a lot of goodies out of the box, like collapsing errors, objects, etc.
Edit: also added a counter keeping track of the amount of errors
N.B. no need to immediately review this diff, I'll import it to phabricator as soon as I can :)
