This refactors the experimental file picker to avoid fs i/o
in as many places as possible to improve performance.
Further, rendering performance is improved by avoiding unnecessary
element state changes invalidating components.
Also, recent files & favorites have been temporarily disabled
due to lack of need for Etcher Pro.
Change-Type: patch
- Replace onClick arrow functions in all components that use them for
efficiency reasons: 300-500% speed-up
- Sort by folders and ignore case for better UX
- Remove use of `rendition.Button` in files, leading to a 10-20%
performance increase when browsing files
- Proper sidebar width and spacing
- Recents and favorites are now filtered by existence async for a tiny
performance improvement
- Make Breadcrumbs and Icon pure components to stop frequent re-rendering
- Initial support for array constraints
- Use first constraint as initial path instead of homedir if a
constraint is set
- Use correct design height on modal, `calc(100vh - 20px)`
- Reset scroll position when browsing a new folder
- Fuse Bluebird `.map()` and `.reduce()` in
`files.getAllFilesMetadataAsync`.
- Use `localeCompare`'s own case-insensitive option instead of calling
`.toLowerCase()` twice on `n-2` files compared.
- Use 16px font sizes in sidebar and files to match design.
- Disable `$locationProvider.html5Mode.rewriteLinks`, which seemed to
take 50ms of the directory changing time.
- Leave file extension as-is in `files.getFileMetadataSync` and the
async counterpart for a very minor performance improvement.
