Merge branches 'master' and '0.9'
Forgot to update version number last update. Fixed.
Add utils.sh checking code.
Run through shellcheck.net. Converted all printf to echo since it's easier, may convert back later if given good reason.
Now use whereis to find the sensors program instead of assuming a path. Also mention help in the readme if the program is not found.
Add more acceptable paths to whereis command, as per further testing.
Merge pull request #3 from Elyrith/master
