Add honcho/test/integration/test_export.py
Sort before iterating through dict items

Causes a failure in Python 3 that I only discovered while writing

Add support for -t/--template option to export

This is a honcho analogue of the corresponding options to `foreman
export` (See http://ddollar.github.io/foreman/#EXPORTING)

This lets you specify a custom Jinja template to be used when exporting
to a supervisord config file.
