Subject: [PATCH 2/3] Implement --version flag

Summary:
Changelog: [Internal]

Adds a basic `--version` command line flag to the RNDT shell. This will be used in code paths (including tests) that need to verify that the shell is executable, but do not need to actually display a window or hand over control to the main shell instance.
