catj should accept stdin input

[ry]

curl https://ci.appveyor.com/api/projects/deno/deno/builds/25856198 | catj

(also can we rename it from catjson to catj ?)

Try:

curl https://ci.appveyor.com/api/projects/deno/deno/builds/25856198 | catj -

There's no easy way to check if there's something to read from stdin in Deno (if there's nothing it will block forever), that's why - is needed.

Oh sorry ! I didn't even see that in the help text. But trying it now, it doesn't seem to work.

> cat log.json | catj -
Usage: catjson [-h|--help] [file...]

Examples:

// print file:
   catjson file.json

// print multiple files:
   catjson file1.json file2.json

// print from stdin:
   cat file.json | catjson -

I just checked and indeed it's not working... I think flag parsing after script name in v0.11.0 might have broken it. I'll investigate in the evening.
