Use Dependency Injection for service initialization

[oh-noey]

Describe in detail what your pull request accomplishes

• Use Dirk as a Dependency Injection (DI) framework to allow for simpler usage of the inversion of control pattern.
• Adds several building block life cycle management systems to abstract away common patterns
  • Service for startup/stop patterns
  • Worker for an async/sync background processors
• Simplifies event handler registration by automatically doing so once added to the DI container.
• Abstract version management concepts via inversion of control
  • Dependents can use VersionInfo to access version related data
• Abstract settings lifecycle management via a Service
  • Eventually it would be good to migrate Settings to be injected, but that is out of scope for now
• Migrate several small startup routines to Service singletons
• Migrate all startup BukkitRunnable implementations to Worker
• TODO: Add unit test
