Use separate compilation. (I don't know if dub support this.)

Also, in my own vibe.d project, I split up the Diet templates across
multiple modules, because they are extremely compile-time intensive. For
example, I had one set of pages dealing with account creation, another
set of pages with the main functionality, so I split them up into two
modules -- since it's unlikely I'll be changing both sets of pages at
the same time. That, plus separate compilation, cuts compile time by
half.  Better yet, I split up front-facing UI code (mainly Diet
templates) from backend logic, so that the Diet templates are not
recompiled while I'm changing only the backend logic.
