Remove chmod on project dir

Modifying the object didn't feel quite right, plus this makes the code a
bit more compact.

Fixes #579.

- Remove size from directories (often always 4K and not very useful).
- Format file sizes to be more human-readable.

* Implement write/read buffers in electron fill

This makes cutting and copy files from the file tree work.

* Implement fs.createReadStream

This is used by the file tree to copy files.

* Allow passing proxies back from client to server

This makes things like piping streams possible.

* Synchronously bind to proxy events

This eliminates any chance whatsoever of missing events due to binding
too late.

* Make it possible to bind some events on demand

* Add some protocol documentation

* Fix hash

* Remove whitespace

* Let people know when telemetry is disabled, change url to https if secure connection

* Remove --no-auth as a http candidate

* Rename variable, change let to const

* Add --socket flag

* Add msg for already bound socket

- Fixes #542

* Remove -h flag for help information

* Add tab after removing -h option

* Remove spaces after --user-data-dir option to line up with other menu items

- Fixes #508

Mac was using its own thing.

- Fixes #535
- Fixes #501
