Updated CHANGELOG

Removed CHANGELOG entry

Using update_column to store the boolean flag to avoid
any side effects with the current state of the project
instance

This method can be used to find multiple projects for multiple paths.
For example, take this snippet:

    Project.where_paths_in(%w{gitlab-org/gitlab-ce gitlab-org/gitlab-ee})

This will return an ActiveRecord::Relation containing the GitLab CE and
GitLab EE projects.

This method takes care of matching rows both case-sensitively and
case-insensitively where needed.

Project.find_with_namespace in turn has been modified to use
Project.where_paths_in without nuking any scoping (instead it uses
reorder(nil)). This means that any default scopes (e.g. those used for
"pending_delete" stay intact).

The method Project.where_paths_in was added so the various Markdown
filters can use a single query to grab all the projects referenced in a
set of documents, something Project.find_with_namespace didn't allow.

The logic of the method was obviously inverted.
