fix(tools/check_for_upgrade): Don't source profile

Reverts #2296, but mostly #1883.

There is no need to source ~/.profile when this script is read. oh-my-zsh writes no configuration data in ~/.profile.

If the user wishes to use data within ~/.profile, then they should source it in another place.

Fixes #2315
Update the list of Heroku Postgres commands
Quote path in case $HOME has a space in it.

I've seen stranger things on OS X, unfortunately.

Disable sourcing .profile when checking for available updates
Respect original PATH definitions on install

The exporting of PATH as a fixed string would clobber any system-wide
paths added to env after installation. Instead, we now read any existing
PATH exports from previous config files and copy those from the user's
bash config, or else default to a basic prepend-only example that
respects the system environment.
Use sed instead

This needs the extra newline character defined in a variable because
shells treat the ${} expansion differently for replacing newline characters.
