Remove 'bin' from global gitignore
Remove 'bin' from global gitignore

I don't remember why I added 'bin' to my global gitignore (maybe node
project builds?) but having it in there has caused me to lose configs
when I do a stash/pull/stash pop from my dotfiles.  Better to just put
'bin' into the projects' own .gitignore moving forward.
