Changed the url for reporting issues to that of the new repo.

It looks like pip 8.x has dropped support for Python 3.2 and is causing test
build problems. Since Python 3.3, 3.4, and 3.5 are supported I don't see any
issues with dropping 3.2 test coverage although it will probably still work.

Pandoc treats both underscores and dollar signs as non-literal
characters which screwed up the manpage.

because tests have been removed

Closes #178.

Closes #156.

The recommendation doesn't work with bash 4.1.5, the code in autojump.bash is fine, so use it here.

I've updated the documentation to notify end users to add compinit to their
~/.zshrc if they want tab completion.

--stat added, jumpstat alias removed.

Options passed to the `j` function will now be passed on autojump. As a result,
directories beginning with `-` are no longer supported.

A -s short alias for --stat is added. Instead of using jumpstat, use `j --stat`
or `j -s` instead.
