* increase timeout for update checks
It seems like, there are lots of them and GitHub is not happy.
So increasing timeout 6x should fix that. In the end there is no need
to check updates every 5 minutes.
Fix#880
* restore check updates on start
* Bump `eslint-plugin-react`
* Add `eslint-config-xo-react`
* Add XO
* Remove eslint-related dependencies, add XO config and use XO as the linter
* Code style: Standard => XO ✨
* Use xo property to ignore files
* Fix remaining errors
* Step 1: move electorn into `app/`.
This is to comply with the suggested directory format of
`electron-builder`: https://github.com/electron-userland/electron-builder#two-packagejson-structure
* Step 2: add build directory with icon files for mac / windows
* Step 3: move all development (web) assets into main directory
* Step 4: add `build` namespace to dev `package.json`
* Step 5: move all dev dependencies into dev file and get rid of
old electron packagers in favor of `eletorn-builder`
* Step 6: target build inside `app/` as everything else is excluded at build time
* Step 7: remove old stuff!
* Step 8: update README
* turn off asar for `child_pty`
