2.0.5: Fix AnnoyingFile issue

• Add error.invalid-argument message
  • Not used by anything in the API, but I end up adding it eventually in my plugins anyways
• Fix AnnoyingFile issue
  • AnnoyingResources wouldn't work because of a change from 2.0.4, this should fix it
• Add missing parameter Javadoc
• Made AnnoyingSender fields public
  • Removed getters too since they are no longer needed, also added Javadocs to the fields
• Bump version (2.0.5)
  • I forgot to bump it for 2.0.4, oops...

Full Changelog: 2.0.4...2.0.5
