v0.1.0-alpha

Changes:
- Implement bootstrapping library for managing several concurrent internal services
- Refactor concurrency model for connections/logical clients and their associated I/O
- Refactor server context singleton
- Refactor error handling
    - Most errors are now gracefully sent to the FSD client directly encoded as an $ER packet,
      enhancing visibility and debugging
    - Most errors are now rightfully treated as non-fatal
- Refactor package/dependency graph
- Refactor calling conventions/interfaces for many packages
- Refactor database package
- Refactor post office

Features:
- Add VATSIM-esque HTTP/JSON "data feed"
- Add ephemeral in-memory database option
- Add user management REST API
- Add improved web interface
- Add MySQL support (drop SQLite support)
