(#996) Create config directory if it doesn't exist

[corbob]

Description Of Changes

Create the C:\ProgramData\Chocolatey GUI\Config\ directory if it doesn't already exist.

Testing

1. Delete C:\ProgramData\Chocolatey Gui\ directory.
2. Launch Chocolatey GUI.
3. Ensure it doesn't error.
4. Delete C:\ProgramData\Chocolatey Gui\ directory.
5. Run chocolateyguicli -?.
6. Ensure Help is output by Chocolatey GUI CLI.
