A new Zplugin extension that exposes binaries

[Sebastian Gniazdowski <sgniazdowski@gmail.com>]

Hello,
normally, when one wants to gain access to execute a script/program,
he copies it to the PATH or adds its directory to the PATH. There is
however a different method: to create a function of the same name as
the binary with the path to it embedded inside the function.

One other method is to create a "forwarder"-script (rbenv calls such
scripts `shims') and copy it to the single, possibly dedicated PATH
entry.

The zplugin extension does this automatically. Example function created:

asciidoctor () {
        local bindir="/home/sg/.zplugin/plugins/zdharma---null/bin"
        local -x GEM_HOME="/home/sg/.zplugin/plugins/zdharma---null"
        "$bindir"/"asciidoctor" "$@"
}

As it can be seen the extension can also install gems and
automatically export GEM_HOME (plus the same for Node, and some other
features).
