Command-line option -w- to switch watch mode off

[fantaclaus]

TypeScript Version: 2.0.3

Please, add a command-line option -w- (or --nowatch or something similar) to override watch: true setting in tsconfig.json file.

It is needed for building a project from the command line on a build server.

This shoudl be covered by #10967.

On a side note, I would actually recommend the opposite. keep your tsconfig.json with no watch and call tsc --watch when needed.

@mhegazy Brilliant! Thanks for the idea! I've put "args": [ "-w" ], into tasks.json. So now it works in watch mode inside VSCode, but just compiles with no watch when started from the command line.
