Add guides on how to add a debugger in VSCode, Eclipse and PyCharm

Coconut Cockpit created YouTube tutorials on how to add an EmmaLua debugger to VSCode and PyCharm.
But he did a "special" approach because a symlink didn't work for him.
In my tests a junction link works perfekt with VSCode.
FlightControl did a guide on how to add a debugger to Eclipse.
We need to wrap up all these bits of informations to create an easy step by step guide for contributors.
Maybe we need to add some code templates for easy integration in MissionScripting.lua, too.
