Instances option allows non number value, starts infinite instances

[thoreinstein]

pm2 --version: 0.12.7
iojs --version: 1.5.1
os: Ubuntu 12.04.4 LTS (GNU/Linux 3.11.0-15-generic x86_64)
os: OS X 10.9.4

Launching an application with pm2 start index.js --name "test" -i 0 performs as expected and launches one instance per core of my machine.

However one missed keystroke pm2 start index.js --name "test" -i o continues to launch instances of the application until kernel panic.

I attempted to run this with debugging on, however calling start with -i o seems to just hang the process and does not log anything to stdout or stderr. This is can be reproduced on both my local MacBook Pro and my server.

I will do my best to try to work on this issue. Unfortunately I cannot do anything until I am off of corporate resources.

Investigating this right now,
