customized shell settings in bash and zsh

My original shell settings based on Paul Irish, which was based on Mathias Bynes

customized shell via Prezto themes largely ported over from previous bash settings

• EDITOR - by default I use Sublime, but this can be modified to another IDE (VSCode/Vim/JetBrains/etc)
• LOCAL_BIN_ROOT - change to correct path of User, points to the ${User}/bin for User executables
• HOMEBREW_CASK_OPTS - can be removed if not using Homebrew Casks/want it moved outside of /Applications
• MACOSX_DEPLOYMENT_TARGET - Setting for xCode cli, will need to update
• BASH_SILENCE_DEPRECATION_WARNING - silences the warning if using bash in OSX - irrelevant if using zsh
