Supposed to be POSIX-compatible. Proved to work in dash, yash and whatever
alpine uses. See https://unix.stackexchange.com/a/371873

This facilitates testing of changes to the core installation code: you'll be
able to do a roundtrip test of install and uninstall using the working code on
your branch.

Controlled by passing $REPO and $BRANCH environment variables to install.sh.

This changes the behavior to default to the binary found first in $PATH,
then checking it's actually in the shells file (/etc/shells).

If that fails go back to the previous behavior, but actually check that
the path obtained exists in the filesystem.

Guard clauses are if constructs that return early if there is an error
that prevents continuing. This way there isn't a big nesting of if
expressions.

Otherwise we risk a situation where a full path to `zsh` is commented, i.e.:

    #/usr/local/bin/zsh

This replaces the currently running process with the new one using `exec`
instead of creating a new process. This way, when the user `exit`s out of
the new shell it will not pop them back into the shell from which ohmyzsh
was installed from.

This will allow us to use tab stripping heredocs with `<<-'.

Add editorconfig file to enforce this style.
See http://editorconfig.org for more information.

This early return made it so the lock wasn't removed, therefore locking out
the upgrade script from ever entering the upgrade routine.

Fixes #6138 

Note: the logic needs some rework.

* Updating Oh My Zsh shop URLs

Linking directly to the Oh My Zsh inventory vs the top-level store with non-OMZ items.

* Updating link to Oh My Zsh products in the install script

* Updating link to Oh My Zsh shop products in the upgrade script

* Getting rid of 't-' in shirts for now

Fixes #7492

* use https everywhere

* use https links on the files that are left

Also, removed some broken links and updated redirections.

Otherwise these files are not sourced:
  1. /etc/zprofile
  2. ~/.zprofile
  3. /etc/zlogin
  4. ~/.zlogin
  5. ~/.zlogout
  6. /etc/zlogout

Quote $ZSH where necessary in install script

`[Oh My Zsh] Would you like to check for updates? [Y/n]: ` does not make sense, 
since answering yes will download/apply the new updates instead of checking for them.

Quick fix to the script not finding git due to hash.
Solves #6697.

This makes things work even on system lacking /bin/sh, such as on
non-rooted Android systems.

When the user is asked to update oh-my-zsh it says "[Oh My Zsh] Would
you like to check for updates? [Y/n]:". When the user agreed to update
the next text would say "Upgrading Oh My Zsh" which is inconsistent
with the question.

 - Need dot `.` for POSIX compliant instead of `source`
 - Use modern syntax for command substitution
 - Fix missing double quotes

Really this time :P

Fixes #4533
