Move internal eval and rename utils to core

Part of this restructure involves splitting out the massive evergreen
folder into a `fun` folder and then a `utilities` folder. To help with
that we've rename the `util` folder to `core`.

The core functions to run the bot have been moved into this folder.
`.source`, `.ping`, and `.int e` have been moved into this folder.
