[Suggestion] Add a Introduced Field to Compiler Options

[kitsonk]

Compiler Options is getting rather complex and for people coming to TypeScript, when the flag is documented prior to the GA of a release, are getting confused, thinking they can use something they can't. (Even those of us who are familiar can often forget). Adding a column that documents in what version it was introduced would help clarity (or add it to the comments).

I'd like to tackle this issue. However, the table columns are currently (mostly) fixed-width

Option      | Description
------------|---------------------------------------
`--allowJs` | Allow JavaScript files to be compiled.

As far as GitHub tables markdown is concerned, this is sufficient:

Option | Description
---|---
`--allowJs` | Allow JavaScript files to be compiled.

Can I add the new column at the end, without preserving the current fixed-width?

Option      | Description | Introduced
------------|---------------------------------------|---
`--allowJs` | Allow JavaScript files to be compiled. | 1.8

Is there a need for the precise build version? Or is the major version enough?
Also, do pre-1.0 versions matter? More, as long as the options are part of a GA release, (as of this writing, 1.8) does it matter which previous version it was available in?
