Better Version Management

[WYVERN2742]

With WebCT close to launch; version info should be handled better.

1. Building to development should include dev/branch/commit on the exe and webpage.
2. Building to production should include version on the exe and webpage.

Both above points should automatically handled.

This makes it easy to see what version WebCT is using just from the page. It's likely best placed as gray text on the left-hand side.
