Replace Babel with TypeScript compiler, switch entire app to TypeScript 🎉 (#1404)
* Switch to using Typescript instead of Babel

* Switch all es6 / jsx file extensions to ts / tsx

* Convert Utils to a TS module from module.exports style module

* Move everything from module.exports to typescript exports

* Define .d.ts files for mailspring-exports and component kit… Yes it seems this is the best option :(

* Load up on those @types

* Synthesize TS types from PropTypes for standard components

* Add types to Model classes and move constructor constants to instance vars

* 9800 => 7700 TS errors

* 7700 => 5600 TS errors

* 5600 => 5330 TS errors

* 5330 => 4866 TS errors

* 4866 => 4426 TS errors

* 4426 => 2411 TS errors

* 2411 > 1598 TS errors

* 1598 > 769 TS errors

* 769 > 129 TS errors

* 129 > 22 TS errors

* Fix runtime errors

* More runtime error fixes

* Remove support for custom .es6 file extension

* Remove a few odd remaining references to Nylas

* Don’t ship Typescript support in the compiled app for now

* Fix issues in compiled app - module resolution in TS is case sensitive?

* README updates

* Fix a few more TS errors

* Make “No Signature” option clickable + selectable

* Remove flicker when saving file and reloading keymaps

* Fix mail rule item height in preferences

* Fix missing spacing in thread sharing popover

* Fix scrollbar ticks being nested incorrectly

* Add Japanese as a manually reviewed language

* Prevent the thread list from “sticking”

* Re-use Sheet when switching root tabs, prevent sidebar from resetting

* Ensure specs run

* Update package configuration to avoid shpping types

* Turn eslint back on - we will opt-in to the TS rules one by one
