Run dfix on the code

Currently discussion in the D community to provide a tool that fixes your code automatically between releases.

The project is done by Brian Schott: https://github.com/Hackerpilot/dfix

I ran it on your codebase, as it's one of the largest I know of. It fixes C-style array declaration (which are meant to die, ultimately) and use of the new alias declaration (which is supposed to be clearer).
