Migrate away from Error-Chain about rexpect

[philippkeller]

@0xpr03 this sounds good. Error-Chain seemed the best choice when I wrote this, but now there are better options.

As I'm currently "out of Rust", I won't implement this. So if you want you can migrate it over. If it passes tests and the example will still work, I'll merge it.

I guess it will also change the api, so I'll just bump the version to reflect this

ah yes, didn't realize this is the same error crate where we have the existing PR for. As I'm not into rust anymore, @0xpr03 would you like to have a look if the PR #29 is good? Unfortunately the contributer was not sure either as the person was new to Rust…

Regarding maintainership you may want to add Rust Bus
I'd also be willing to help out (which is how I started maintaining notify), but I'm probably not the most proficient with this project, just using it at work.

@0xpr03 thanks for pointing me to rust bus. I've invited rust bus as maintainer now, let's see what happens!

Isn't #29 exactly what we want then ?
