Does not close port on exit

When exiting "examples/mycroft_master.py", it does not close the used port. I have to find it with ps aux and kill the process.

I know it's not a major issue, but I hope any I put on here will be welcome.

Thanks guys for your work

you are correct that the twisted reactor is not closing properly, i think this has been reported in one of the other repos

It's a somewhat important bug to fix, you can't exit with ctrl+c either

with the tornado rewrite this no longer applies
