Allow non-interactive mode

[aanno]

Currently ogar is spawning a asyncconsole. When I try to start it with no TTY attached

/usr/bin/node src/index.js </dev/null

the following error appears:

TypeError: this.stdin.setRawMode is not a function
at new AsyncConsole (/home/ogar/Ogar/node_modules/asyncconsole/index.js:24:12)
at Timeout._onTimeout (/home/ogar/Ogar/src/index.js:50:17)
at ontimeout (timers.js:365:14)
at tryOnTimeout (timers.js:237:5)
at Timer.listOnTimeout (timers.js:207:5)

This is because setRawMode is only available for TTYs (see nodejs/node-v0.x-archive#8204)

Please allow to start ogar non-interactive, i.e. without an asyncconsole.

Use this version of the index.js.

@aanno Actually, there is a mode. Do node index.js --noconsole
