Ugly fix where we have to copy two migrations as new migrations so that
they are run and fix past mistakes.
Have to rename the migration.
Added link to outreach.
Upgraded PDF.js to new version.

This version has changed text layer API.
Upgraded dependencies.
Merge branch 'development' of github.com:peerlibrary/peerlibrary into development
Fixed importing of PDFs in Safari. Fixes #627

Not sure why blob was added as a dependency anyway. It should be used
only when testing, to fix tests on PhantomJS. But now we are putting it
as a proper dependency of those packages which need it so things work
correctly when testing them. We are not yet using it in production,
probably those browsers have larger issues anyway. We could use it in
production now though, because new version of meteor-blob has now a
version which does not break Safari anymore.
Updated meteor-file to version which better handles errors.
Make sure we use home directory.
Debugging Dockerfile.
Debugging Dockerfile.
Fixed version.

It seems that for some reason HOME variable was now set to /root and was
not before. Maybe with the release of new Debian version. Or maybe it
was passed in by new Docker Hub version.
Fixing paths in Dockerfile.

Added information about the weekly meeting.
