Save Projects to a config file and create Forge Project

[Lanpingner]

Reads all projects from a config file "Json"

News

1. We have a project manager that handles create/delete projects
2. Last open is now saved to the config
3. Projects are create able on the UI and being saved to the config
4. FORGE project download and create the folders(unzip) update the .properties (not the src folder)
5. Read projects at startup once (no double read)
6. Forge Project Creation uses Path instead of String to support all Platforms (tested in Linux)
7. Last open shows in a Friendly Format ("Today", "2 days ago" .....)
8. New Projects view to show Projects in a better way (we need a designer :) )
9. Filter Projects now working

Current config dirs

• Linux $HOME/.config/Railroad/config.json
• Windows %APPDATA%/Roaming/Railroad/config.json

TODO

• Auto append Projects on new creation
• When Filter it should not read again the Projects (unnecessary work)
• Remove Projects
• Save Unique ID of the project to the file for delete/modify reasons
• Add Last Opened to the save file
• Create Forge Project and save
• Setup .properties for Forge Project
• Setup Forge project src dir (not the java files)

ISSUES
ExampleMod.java is not updated because idk how we will handle we could use javaTools like here
Parse Java

Mostly just minor changes, so a great PR overall. I'll try and get around to making a code-style document and ideally an intellij formatting export that people can import and use.
