Format EVERYTHING.

Hopefully this will make the source code less horrendous and actually
readable.

The command used was:
```
astyle --suffix=none --style=allman --attach-extern-c --attach-closing-while --indent-switches --indent-after-parens --pad-oper --pad-header --unpad-paren --align-pointer=name --recursive './*.cpp,*.hpp'
