One alphabetical reordering in the docs/README.md
:memo: webContents, Tray -> Tray, webContents
If I get it right, only API TOCs should be ordered alphabetically,
so I've left other ones (Guides, Tutorials, Development) untouched.
I'm not so sure about API TOC Intro (three links below the "Synopsis"),
tell me if they should be sorted alphabetically too.
