Merge The File&Game Servers Into One Module (#519)

* Merge The File&Game Servers Into One Module

* Make SettingsLoader A GameConstants ConfigLoader
If A Config File Isn't Used, The Server Will Fall Back To The Defaults Set In GameConstants.java

Config Files Can Be Loaded With The "-c/-config configfilelocation.json"
Added A Default Prefilled ServerConfig.json

* Update ConfigLoader

* Bring Back Independant "Secrets" Loader For External Password Stuff
* Added A Bunch More Vars To The ConfigLoader
* Included A Sample "Server Config"
* Also Updated README.md As Parabot Is No Longer Maintained & We No Longer Have A FileServer Module

* Bundle FileServer with Server (docker)

* Remove /udp and http port

* Update .gitignore

* Move FileServer from `org.apollo.jagcached` → `org/apollo/jagcached`

* Tidy GameConstants & Add More Vars To ConfigLoader

* Organised Up GameConstants A Little To Separate ConfigLoader Vars From The Rest
* Added Some More Variables To Be Loaded Through The ConfigLoader

* Fix A Derp Caused By Laziness

* Add -c/-config arg to README.md

* Enable FileServer By Default
