Add Bundler and Rake gem
Add Rake tasks and ignore log file
Fix glaring inconsistency in `rake stop`
Regroup Rake tasks

- Add server namespace and put stop/start into it. You can now
  call these tasks with `server:stop` and `server:start`.
- Add server task which toggles between stop & start based on
  existance of a PID file.
- Add logs:purge task for removing & retouching the `log` file
  at the root of the repo.
