Title: Improve shell detection.

I copied over the improved shell detection from rbenv-init. plenv-init wasn't picking up my zsh shell correctly as it was simply reading from the $SHELL variable.

There are additional changes to rbenv-init mostly around fish shell and completion commands, but I left those out for now.
