vscode file changes, xmodel selector fixes

vscode:
- moved vscode files into sub-directory .vscode/tracked/ so the user has to drag them manually into .vscode/ (untrack files inside the vscode dir so I can add them to gitignore on the next commit -> will allow custom vscode settings)

xmodel selector:
- fixed a nullptr assert for bad / default xmodels
- fixed up/down arrow scrolling if textfilter is active
