This commit refactors the python code in diskimage_builder slightly. This is
in preparation for a larger review that adds more functionality to the python
code, namely the ability to apply elements to the current system as opposed to
a chroot. Further, the refactorings can stand on their own for better clarity.
They include:
- renaming elements.py to element_dependencies.py. Adds clarity about the
purpose of this module.
- updating other code for this rename.
- move tests into a tests submodule.

bin/element-info accesses it's library via a symlink:
bin/diskimage_builder -> diskimage_builder
This causes the relative path in elements.py to be
incorrect.
element-info silently fails in this situation, because
it allows missing 'element-deps' files, so that these files
may be optional.
This change causes element-info to fail explicitly if $ELEMENTS_DIR
is not set, as it now is when called by diskimage-create, and
adds tests reflecting this behavior.

Per http://wiki.openstack.org/ProjectTestingInterface we enable all
of the commands except build_sphinx because we do not have any sphinx
documentation as of yet. Includes babel support though there are no
properly internationalized strings just yet.
