Bug 1234615: Check that resized image files are viewable by user

When exporting via Html export process - if not then ignore the file

To test:

1) Add an image block/file to a page and set a width value

2) Go into db block_instance table and change the artefactid to an
image that is owned by another user

3) Reload the page - you should see the image block but not the
attached image

4) Export the page as HTML, either as full or standalone

Before patch - you will end up with image file in the files/extra/
directory

After patch - you should not get the image in the files/extra/
directory and you should get an info warning 'Unable to copy artefact
file ***' on export page.
