The core setup files for Emacs Siren which lives in the core directory followed a `siren-*.el` naming convention, which is the same as the naming convention for modules. This means that the `modules/core/siren-packages.el` module for adding packages for Emacs package development, was not being loaded due to it's name conflicting with `core/siren-packages.el` which sets up and configures the packaging system. So all files under the root `core` directory now follow a `siren-core-*.el` naming scheme, meaning modules should no longer conflict with core files.
