Switch to relative imports

The relative imports make it clearer what code is within the project and where
it's coming from.

Remove noop conservancy.context_processors imports.

You'll note this source doesn't exist in Git.
There's a reason for that.

Add sitefundgoal to top level view context.

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.

Generate JSON output of a fundraiser data

Allow public interface to query the fundraiser data.

Just quit it with this relative import stuff.

While I think these relative imports seem to be valid for the running
application, I am having trouble with the django-admin applications
regarding them. I don't see this syntactic sugar as absolutely
essential, so I'm just going to change it now.

Initial hack at a fundraising goal application.

This simple application will simply store the code name and the to goal
of each fundraiser. The so_far number will likely just be updated by
some external script, modifying the appropriate entry in the SQL
database.
