Implementeer RedisTaskStorage en andere features (#4)

Browse Source 
Add 'addTasks' method to `Tasks` class

Implemented basic RedisTaskStorage.

- Fixed bug where worker is not provided with bootstrap by ShellExecutor.
- Added composer and Redis to Dockerfile
- Added more output to ParallelSuperVisor

Updated config format.

Implemented changes to binaries. Binaries now accept a 'bootstrap' argument, allowing the developer to load a custom bootstrap from the project they're working on.

This allows Async to run in the same environment as the project it's part of.
