orfeotoolbox : update python variant

[julien.malik@…]

The python variant compiles and install a new module called "otbApplication".

The module "otbApplication" loads plugins currently located in /usr/lib/otb/applications. They are named 'otbapp_Something.dylib'.

For them to be properly detected and loaded, the env var ITK_AUTOLOAD_PATH must be set to /usr/lib/otb/applications before loading python. Not convenient at all. To ease the process, I updated the debian package recently to :

• install in a subdir of "site-package" with OTB_INSTALL_PYTHON_DIR, and not in site-package directly
• create an __init__.py at install time which import the right thing and then set up the env var.

Something similar shall be done in the Portfile.

The __init__.py file content can be found here: ​http://hg.orfeo-toolbox.org/OTB-DevUtils/file/tip/Packaging/ubuntu/OTB/debian/python-otb.postinst

To test the fix, this :

python -c "import otbApplication;print otbApplication.Registry.GetAvailableApplications()"

should output a non-empty list of strings.
