Get terminals working

Browse Source 
- Instead of a single listener per terminal that handles all events VS
  Code now has a single listener per event that handles that event for
  all terminals.
- Refactor Terminal to extend TerminalProcess to avoid duplicating
  methods. This required some modifications to TerminalProcess to access
  the pid and title and to set the ID.
- Remove our async change to shutdown. This was necessary to avoid
  disposing too early but shutdown already calls dispose so it turns out
  we didn't need to call it ourselves.
- Rename methods to match the command strings.
- Fix getting system shell (uses process.env).
- Use a single bufferer. Since it already supports buffering for
  multiple terminals there's no need to have one per terminal.
- Remove replay/reconnect logic. It's broken and unused so there doesn't
  seem much point in trying to refactor it to fit the changes right now.

While terminals work now there are still a lot of todos.
