Replacing pow with puma-dev

I got tired of pow misbehaving sporadically after system updates or bundler updates – I never got to the root of the cause – so I switched over to use puma-dev in development. Using tunnelss was evidently also too tedious…

1. uninstall pow:

   curl get.pow.cx/uninstall.sh | sh
   

2. install puma-dev:

   brew install puma/puma/puma-dev
   sudo puma-dev -setup
   

3. move .pow to .puma-dev

4. The pow uninstall might have missed something so I needed to do:

   sudo pfctl -F all
   

   (Mentioned here)

5. Add puma as development dependency in every rails/sinatra/rack app.
