refactor: restructure my Code directory

I recently restructed the contents of my `~/Code` directory so that
repositories are grouped by their provider and organisation.

For example, my `dotfiles` are now located at
`~/Code/github.com/opdavies/dotfiles`.

Likewise, `build-configs` is now located at
`~/Code/github.com/OliverDaviesLtd/build-configs` as it's within the
`OliverDaviesLtd` organisation.

As well as `~/Code/github.com`, I also have `~/Code/bitbucket.org` for
Bitbucket repositories. These are also grouped within subdirectories for
each organisation.

This change means I need to update any reference to the old `dotfiles`
location to the new one and I can update the `t` function to adjust the
min and max depth it uses to find directories.
