composer/installers dep workaround

Moved to end of requirements, to work around a bug in composer - see https://github.com/composer/composer/issues/1147. This caused the dependencies to be installed in the wrong folder because the custom 'silverstripe-module' instructions hadn't been loaded at the time the core modules were installed via composer.

BUG ShowUnpublished checkbox with initial state not working

If ShowUnpublished checkbox initial state is checked, the history
doesn't show the unpublished versions up front. The user would need to
uncheck the box then check again, as only the change event would handle
the toggling of showing unpublished versions.

Moved the ShowUnpublished handler into a separate entwine class, and
run the same toggle code onmatch, as well as onchange.

Update doRollback messages to work well with the new reverts.

Currently reverts are not creating the new versions anymore - they are

not correct.
