Implement APL Logging API

[noahc3]

• Switch assembly metadata tags in use
• Implement Logger in APL/Core
• Refactor all logging through this API (plugins no longer log through Harmony FileLog)
• Disable Harmony.DEBUG by default (users can enable with HARMONY_DEBUG if they want it)
• Implement log levels (NONE, INFO, WARNING, ERROR, DEBUG)
• Logging output targets:
  • Log to stdout by default
  • Log to file if APL_LOGGING= env variable set
  • Implement file log rotations up to 5 logs

Potential improvements for a future PR not addressed here:

• Would be nice to capture Harmony debug logging if APL_LOGGING=DEBUG and mix into apl.log alongside APL Logger messages.
• Would be nice to be able to configure file logging in a settings UI in addition to env variables.

Resolves #19
