Evict devices from cache when unreachable

[mpdifran]

I've updated my wemo light switches to the latest firmware recently, and now ouimeaux is crashing when I run wemo status in the command line. I can run wemo list just fine, but it only lists 3 of my 4 switches. Here's the output when I run wemo status:

Switch: TV  1
Switch: Pot Lights  1
Switch: Bedroom     Traceback (most recent call last):

Try running "wemo clear" first. Possibly the cache has an outdated entry. — Ian

Yup that was it, thanks!

I've made the retry mechanism disabled in command-line mode, and I've set it to ignore devices that aren't reachable. Hopefully that leads to a more natural interaction. It'll take some major refactoring to clean this up properly.
