Deals with app error page, saving true error instead.

Upon app failure, Heroku returns HTML "Application Error" page.
Finding HTML page in .gitignore is confusing, so I replaced
`-s` with `-f` in curl calls, which cuts such output.

Replace instead of addition as no progress meter outputs either.

It is practically impossible to teach good programming style to students that have had prior exposure to BASIC.  As potential programmers, they are mentally mutilated beyond hope of regeneration.

* Simplify hub check and hardcode aliasing

* Update hub completion

* Refactor pyenv plugin to use PATH

NOTE: The scrapper was previously included, but due to the website it scrapped
being dead it's no longer useful. See #3642 for the code.

`source ~/.zshrc` is a bad practice, it doesn't make sure that the full
zsh session is reloaded and it may have side effects.

Use `$SHELL` as the path to zsh if it exists (this will fix edge cases
where the zsh used is not the first on $PATH). Otherwise, use `zsh`.

* Always try and start gpg-agent, with --use-standard-socket it will try and use a standard socket directory. It won't start multiple agents if agent is already running. In addition, XDG_RUNTIME_DIR isn't always set

* ssh socket if broken if --daemon is run again, so onky start if we don't have a socket

* Removed unnecessary allocation of GPG_SSH_AUTH_SOCK
