Renaming "src" directory to "pyactiveresource"

[Dylan Smith]

With this change, the following will work at the top level of the project.

    $ PYTHONPATH=. python pyactiveresource/tests/alltests.py

    $ python

    >>> import pyactiveresource

Currently I am using a symlink to make the above work.

    $ ln -s src pyactiveresource

However, just renaming the "src" directory would make using the library in development more intuitive.

This will also require removing package_dir in setup.py for distribution:

diff --git a/setup.py b/setup.py

--- a/setup.py

+++ b/setup.py
