2.0.3: Reworked AnnoyingMessage replacements

• Fix Gradle placeholders
• Add loadMessages() and more changes
  • messages.yml loading has been moved into it's own method, AnnoyingPlugin#loadMessages()
  • Removed translating some of the message options keys into their strings from messages.yml
  • Getting missing dependencies and their names improved
• Completely reworked AnnoyingMessage replacements
  • Added AnnoyingMessage#Replacement, which holds information about a replacement
  • Added #splitterPlaceholder which will keep the parameter placeholder splitter cached
  • #replacements is now a Set<Replacement> instead of a Map<String, String>
  • Reorganized some methods
  • Parameter placeholder replacements will no longer be processed immediately. This will ensure that all parts of a message (sub-messages, JSON components, etc...) will get the replacement processed.
• Adjusted reload logic
  • Will no longer use PluginManager to reload the plugin. Instead, it will only reload AnnoyingPlugin#messages and then run AnnoyingPlugin#reload(), which a plugin using the API can override.
• Multiple strings for AnnoyingSender#argEquals(int String...)
  • Instead of doing annoyingSender.argEquals(0, "string1") || annoyingSender.argEquals(0, "string2"), you can now do annoyingSender.argEquals(0, "string1", "string2")
• Add PlayerDamageByPlayerEvent (#1)
• Make Jetbrains Annotations use compileOnlyApi
• Change PlayerJoinEvent example to PlayerDamageByPlayerEvent
• Add attack message key
• Bump version (2.0.3)
