Patch for versions after 2.1.2.04 (Tested on 2.1.2.10) (#84)

Safety improvements:

- `sandbox_run.ps1`: Added a check to ensure the
  script runs only if the username is `WDAGUtilityAccount`.

- `Sandbox.wsb`: Disabled `ClipboardRedirection` to patch versions after
  2.1.2.04

- `Sandbox.wsb`: Enabled `vGPU` for better video performance.

Fixes #65.
