Tidy up project structure, fix bug with edit logging (#47)

The project structure has been changed because the previous one had
everything in 1 folder. From this PR onwards, the following is true:
- The source code is stored in `src/`
- `*.resx` and `Messages.Designer.cs` is stored in `locale/`
- Documentation is stored on the wiki and in `docs/`
- Miscellaneous files, such as dotfiles, are stored in the root folder
of the repository

This PR additionally fixes an issue that would cause logs of edited
messages to not be syntax highlighted. This happened because the
responder of edited messages was changed to use the universal
`InBlockCode` extension method which did not support syntax highlighting
until this PR

This PR additionally changes CODEOWNERS to be more reliable. Previously,
it would be possible for some PRs to be unable to be approved because
the only person who can approve them is the same person who opened the
PR.
