The directory nesting is unnecessary here and confusing to navigate. I've moved
all apps to the project subdirectory, currently called "www", but soon to be
renamed "conservancy".
I've also moved manage.py to the top-level directory.
The base template now has access to the fund-raising goal that will be
displayed site-wide. The view here must provide it in the context for
access everywhere.
Furthermore, we need a local context processor to make sure it's in
context everywhere, and we have to make sure that context is properly
passed along.
This code is a bit cargo-culted in, based on what I read in various
places about adding the Request context.
