Python part of multidim. array support for RNA complete.

Multidim. arrays can now be modified at any level, for example:

struc.arrayprop = x
struc.arrayprop[i] = x
struc.arrayprop[i][j] = x
struc.arrayprop[i][j][k] = x
etc...

Approriate rvalue type/length checking is done. 

To ensure all works correctly, I wrote automated tests in release/test/rna_array.py.

These tests cover: array/item access, assignment on different levels, tests that proper exceptions are thrown on invalid item access/assignment.

The tests use properties of the RNA Test struct defined in rna_test.c. This struct is only compiled when building with BF_UNIT_TEST=1 scons arg.

Currently unit tests are run manually by loading the script in the Text Editor.
Here's the output I have: http://www.pasteall.org/7644

Things to improve here:
- better exception messages when multidim. array assignment fails. Those we have currently are not very useful for multidim.
- add tests for slice assignment
