Added new modular "injector" sytem which will allow myself and others to create injector add ons which will allow you to use placeholders in various plugins. To use this system, you will just drag and drop the injectors you want enabled inside of the PlaceholderAPI/injectors/ folder.

This system is completely optional and if you do not want to even allow the plugin to initialize the Injector sytem at all, you just need to set injector_enabled: false in the config file.

Injector settings will refresh when /papi reload is used. You can enable / disable the entire system on the fly.

Injectors will be available soon.

For developers:
This injector API is not finalized yet and there may be changes to the current implementation. I will release documentation on how this API works when the implementation is set. For right now I am still playing around with it.​
