Removed exception on Windows for finding ImageJ

Previously FindApplication would throw an exception on Windows if
it could not find ImageJ.  Now it will simply return an empty
string.  Thus if the user specifies a different image viewer
via the SITK_SHOW_COMMAND environment variable, execution can
continue.

If ImageJ is not found and there is no SITK_SHOW_COMMAND given,
an exception is thrown later on.

Adding Python support for SetPixel for Vector and Complex image types

Copied code from __getitem__ to __setitem__ to perform bounds and
error checking in python and to produce more friendly exceptions. The
behavior should be the same, except the index element types in python
must be int, it's possible float or long types were used
before. __setitem__ now call SetPixel to follow the whats done in
GetPixel.
