Title: Fix Blog Dependency. Use Blog module without widgets module

If BlogManagementWidget class implements PermissionProvider,
Blog module can't be used without Widgets Module.

In Admin, all Classes, that implements PermissionProvider are loaded,
but no widgets class (if the widgets module isn't installed)
