Show password in installer fix (#1002)
Bump Fork version.
Merge branch 'master' into doctrine
ReAdd has_children variable that got lost during refactoring.

Two differen pull requests: #931 and #935 altered the Fork cache
building process. This commit fixes a line that got lost while fixing
merge confilicts.
Merge branch 'master' into doctrine
Fetch ContentBlocks with doctrine in the frontend.
Remove unused datagrid query.
Make the ContentBlocks copy action use doctrine.
Use Doctrine to install the ContentBlocks module.

We don't use a handmade install.sql script anymore. The Doctrine
SchemaTool can build the needed sql for an entity and run the
installation process.
Cleanup the installer some more + add credits.
Change fieldname from hidden to visible.

The label for the field is "visible", so it's more logical to also call
the field "visible". I also fixed the logic.
Don't persist objects to update them.

This is only necessary when adding a new object. Existing objects are
automatically updated in the database when running flush on the
EntityManager.
Add Entities for the Faq module.
Sometimes, multiple classes will be inserted at once.
Add Faq tables and default categories with doctrine.

Also: refactor the FAQ installer a little to have cleaner and more
understandable methods.
Load Faq Categories from Doctrine.

Note that the num_items field is not shown now. This should require
a custom query builder, which is not supported in
BackendDoctrineDatagrid yet.
