The `commands[autojump]` block errs out when autojump is not found, and the rest, which is intended to be used for loading `autojump`, does not get executed.

I was adding autojump on a new machine and annoyingly forgot that autojump
was to be installed on its own. This may be helpful.

* Fix autojump sourcing on OSX with Macports

The last version of autojump available on Macports does not have
anymore different shell scripts (.sh, .zsh, .bash ...) to be sourced
but just one autojump.sh that takes care of that located at
/opt/local/etc/profile.d/autojump.sh

fix # 4625

* Fix bug with macports autojump on OSX.

autojump installed from github has mv the autojump.zsh to $HOME/.autojump/share/autojump/autojump.zsh

Users may install their own version of autojump to override the system
installed version.

Starting with autojump 21.0.3+ there is no file autojump in etc/
directory, so we source the autojump.zsh file directly. Version 20 has
it as well, so there should be no problems with earlier versions.

Comments on autojump's update in homebrew:
https://github.com/mxcl/homebrew/commit/5da9c4d5eb38e6abb516ba648898fb374ec360cd#Library/Formula/autojump.rb

If you manually install autojump as advised by the autojump README by running
the install.sh script, it will install by default to $HOME/.autojump.

Add an extra case in the zsh autojump plugin to find the new file and stop a
syntax error in the else clause every time a new zsh starts (running brew when
brew does not exist).
