Support for renamed VMs?

[mwise]

First off, thanks for ievms and iectrl. We've been using ievms at GoNoodle (also in Nashville!) to test our apps for a while now.

It looks like iectrl only supports VMs that are named according to the ievms conventions (e.g. 'IE9 - Win7'). In testing our CI setup, I've cloned some VMs and renamed them. As such, it looks like iectrl can't find them and parses the names (e.g. 'IE9 - Win7 INTEGRATION') as having invalid OSes, etc.

Would you be interested in a PR that allows iectrl to find these VMs (which are functionally ievms VMs, I believe)? If you can recommend an approach, I can try to whip one up.

Also, I didn't see any build instructions in the README, so if you could provide that, that would be helpful.

Thanks,

Mark
