Make it work well with Ubuntu

[jinalskothari]

It is my understanding that on Ubuntu the ~/.bashrc file needs to be update instead of ~/.bash_profile. I don't know much shell scripting, but could this script detect the distribution and make the changes in the right file?

If lsb_release tool is present on system,
OS=$(lsb_release -si)
ARCH=$(uname -m | sed 's/x86_//;s/i[3-6]86/32/')
VER=$(lsb_release -sr)

$OS is equal to 'Ubuntu' on my Ubuntu 14.04 release. Not sure which other versions would this work with.

This overlaps with #15 - which I just picked up to look into it. I definitely would like to see this as well.
