Add iterm2-shell-integration

[decayofmind]

Description

Some time ago I created a Zsh plugin to install iterm2 utilities. Now the author of iTerm2 moved those utilities and shell integration to a dedicated repository, naturally making my plugin not needed anymore.

• My entries are single lines and are in the appropriate (plugins, themes, or completions) section, and in alphabetical order in their section.
• The completion/plugin/theme has a plugin file in the repository, it is not just bare instructions to be added to .zshrc
• Any added completions have a readme and a license file in their repository.
• Any added frameworks have a readme and a license file in their repository.
• Any added plugins have a readme and a license file in their repository.
• Any added themes have a screenshot, a readme, and a license file in their repository.
• I have stripped any leading and/or trailing zsh-, zsh-plugin and/or oh-my-zsh- substrings from the link name. This makes it easier to find plugins/themes/completions by name by preventing big clusters in the O and Z sections of the list.

I don't see a plugin file in the repo - without one, ZSH frameworks can't automatically load it.

@unixorn So, should I just remove my plugin without adding a replacement, right?

[unixorn]

I added a plugin.zsh file in gnachman/iTerm2-shell-integration#15

Once that's merged, ZSH frameworks will detect it and it will add the plugin's utilities directory to the user's $PATH automatically.

Amazing work @unixorn !

One small thing - It's not only binaries but also some helper functions to source under shell_integration/zsh, so the plugin file in PR needs one more line to add:

source "${0:h}/shell_integration/zsh"

Going to go ahead and merge this. If gnachman/iTerm2-shell-integration#15 doesn't get closed in a reasonable amount of time, it might be worth updating your old plugin to load https://github.com/gnachman/iTerm2-shell-integration as a submodule and then its plugin file could add the utilities to $PATH and source the helper functions.
