Add banking integration overall architecture diagram

Note: this diagram covers the banking integration work as a whole, not
only the CiviBanking extension. With CiviBanking forming the common
framework for the banking integration work, it seems the right place to
put such general documentation.

The diagram is stored as an uncompressed dia file. Hopefully this gives
somewhat more useful diffs than the (default) copressed files... Plus it
should make the repository smaller (as opposed to the working copy),
because this way delta compression can be applied between revisions.
Add extension skeleton

Mostly auto-generated with Civix; manually filled in the blanks in
info.xml. (These are a first take -- might need some tweaking before
release...)
Add AGPL license text

We do not have any serious source files yet to explicitly reference the
license -- but soon we will. Also, some of the minor bits (like the
description in info.xml) might already by covered by copyright...

I'm not sure about the copyright status of the Civix-generated files.
Add release infrastructure

The Makefile automates packaging of releases. First, the release version
is extracted from the top of the NEWS file, and updated in info.xml
accordingly. (Along with the release date.) Next, all files tracked with
Git are packed into a .zip archive inside the build/ directory.
