[RFC] System.version - retrieve the current Wren version string

[joshgoebel]

Reference: #998, wren-lang/wren-cli#95 Re-opening this as an issue so it is not lost.

The original suggestion from @robloach:

---

System.version // => 4000

It returns WREN_VERSION_NUMBER. Was thinking of retrieving the string, or having version.major, version.minor, but I think keeping it dead simple like this is best.

---

I also think returning WREN_VERSION_STRING would be fine also.

That original PR returned the Num 4000 :wink:
