Changes search pattern for Storm version

[Darkless012]

Fixes issue 254

I actually thing the correct fix here would be to change this line to be:

return parse_version(re.findall(pattern, res.stdout, flags=re.MULTILINE)[0])

since we really only want to match it at the beginning of a line.

Indeed. Made new commit. Tested locally - works also.

Thanks for the fix!
