Work around OTP applications which do not respond

[rickpayne]

A workaround for #60 - a bit of a nasty hack that works for me. Feel free to improve ;)

Thanks for this @rickpayne 👍 I think it's a great addition! But I think we would need to indicate the timeout in the UI - currently the application will be present but with no nodes in the tree.

I've left one comment regarding the code itself 🙂

Ok, I'll fix the current pull. Do you want me to look at indicating the fact that application timed out? It'd be a while before I get a chance...

IMO that'd be great to have in the same PR, no rush 🙂 Thanks!
