PEP8: Addressed line break in bloch.py by refactoring hiding of labels

In order to make the code in bloch.py PEP8 compliant and a bit more
readable I refactored the functionality to hide ticks and labels into
a helper function.

Make code pep8 compliant
Allow for Qobjs that do not conform to standard objects in quantum mechanics.

Added the 'other' type for qobjs.  This allows for, among other things,
tensoring kets and bras with operators (per Arne's request).  This may
cause some issues elsewhere but the tests pass just fine.
fixed namespace problems
replace tabs with white spaces
Updated Copyright to 2013
NEW: 3D Bloch sphere using mayavi

still needs some work done
added function state_index_number (reverse of state_number_index)
Merge branch 'master' of https://github.com/qutip/qutip
experimental implementation of general partial transpose
fixed a few coding errors in mc correlation.
added if __name__ == '__main__' to avoid that a sphere is generated when the file is imported
remove debug print...
add partial_transpose import to __init__
