Non-Meaningful is defined as:

- no result from diff -uw
- line changes only from diff -uw
- removal of escaping (probably caused by devs adding |escape to the
  master templates and evonne having copied the old one)
- diff, but caused by new features on master in the templates and not in
  evonnes copy (eg plugin config page has disable links now)

It needs reparenting off the raw theme. And it's broken as it stands as it was developed against 1.1. But we can fix it.

The 'default' theme is to come back shortly.

Strips down the default theme to a very bare minimum, to allow better theming.

The next commits will move this theme to 'raw', and commit a new default theme that looks mostly like the old one.

Half of this (the base library part) was already on master.

Import refactor: moved the transporter classes out of files importer and into base library

very manual cherry of f5c4ed7b

reworked to live in new import/file plugin

Original commit message:
not strictly LEAP related: refactored mnet import stuff into new Plugin architecture.

Remove ?> marker from config-dist.php, which will prevent people breaking their site with whitespace issues.

Only changing this file because it's the one people touch the most.

It's still really basic, but at least now it doesn't look stupid when a user hasn't filled out most of their resume.

Include all stylesheets in the theme hierarchy so the progress bar looks correct even when using a child theme.

This patch changes the behaviour to be thus:

- If the artefact now has no parent, we can safely remove all records in the APC
- If it does have a parent, insert a non-dirty record representing that relationship
- Mark all other rows referencing the artefact as dirty - we can't make any more conclusions at this point.

The cronjob will come through and clean up the dirty rows, as it always has done.

How were we not doing this before?!
