Reorganized ProgressGuildAsync to better show its process instead of
having pieces of it scattered. Also improves performance by performing a
check before doing birthday processing.
Additionally, other parts of the file were condensed slightly.
All existing VB code was 'translated' to C# as closely as possible, with
minor changes and additional notes. Currently untested and likely
broken.
Further commits will go toward making overall improvements until this
version replaces the currently existing code.
