Access control

[sbrl]

Private wiki owners may not want other people to read their wiki content. We should add support for private wikis.

• Require login to view pages
• Add support for moving the root in which files are stored (to prevent people from circumventing the wiki itself) - Issue Allow the directory in which Pepperminty Wiki stores stuff to be changed #37
  • Make sure that we proxy the 'original image' button if access control is enabled, as the web root will likely have been moved to somewhere inaccessible from the web

The core has now been updated to support the new $settings->data_storage_dir. It hasn't been fully tested, but it appears to work.

The modules, however haven't been updated. They will be done one by one, it's a big job!

All the modules have been updated. Not all of them have been tested though, so any testing anyone can do would be a great help! I want to find as many bugs as possible before I release version 0.9.

Done! You can restrict access to your wiki by using the new $settings->require_login_view setting.

I think I've secured everything - you shouldn't be able to view anything without logging in when that option is enabled. If I've missed anything, file a bug and I'll mark it critical (see these comments on issue #40).
