copy files from wp-includes/export verbatim
copy wp-includes/iterators.php to export/iterators.php
load Oxymel via Composer
load export classes via Composer
first pass at loading and using the export API

* replace --file_item_count with --max_file_size
* --verbose is ignored, for now
add _wp_export_build_IN_condition() helper
log each exported file path

had to copy over the whole WP_Export_Split_Files_Writer class.
remove --verbose parameter

The idea is to be reasonably verbose by default and completely silent
when --quiet is passed.
Restore af65fe41c8d3b9df3c1fb1461fddf92ac165fde5, which I accidentally overwrote :(
set Oxymel to version 0.1.0
merge master into export-api branch
Merge branch 'master' into export-api
replace VerboseExportWriter class with 'wp_export_new_file' hook
behat: fix import by making the export message match the expected format again
Merge branch 'master' into export-api
behat: check STDERR when running `wp export`
Support for global `wp-cli.yml` and `wp-cli.local.yml` configs
Adds --skip=image_resize to 'wp import' command.

Gives import user the option to skip image thumbnail generation during
image attachment import. Image resizing is extremely CPU intensive and
makes imports run much slower, especially during test runs that don't
necessarily require all image sizes. Image resizing can always be
deferred post import by running the 'wp media regenerate' command.
Re-factored patch to work with PHP < 5.4.
Allow db export to accept all mysqldump args
