ESLint 4.8.0 discovers a lot of error related to formatting. While I
tried to fix as many of them as possible, a portion of them actually go
against our coding style. In such a case, I've disabled the indent rule
which effectively leaves it as it was before ESLint 4.8.0.

Additionally, remove jshint because it's becoming a nuisance with its
lack of understanding of ES2015+.

Get rid of global APP.conference.screenSharingPromise.

* fix(react/participant): store display name in redux

* feat(remotecontrol): Add option to display the authorization dialog in meet

* feat(remotecontrol): Enable ESLint and Flow

Improves naming.
Fixing typos.
enableLegacyFormat param was working like disableLegacyFormat.
Improves the structure of transport/index.js

For lack of a better word/phrase, I'm calling all changes coding style.
I'm targeting readability through naming and syntax.
