move from LGPLv2 to GPLv2, as this is not a library lets use GPL.
file is already in Resources/Licenses.
add gplv2 text.
update comments.
add correct reference to License resources.
add script to generate License resource from the gplv2 file.
add run script to build license and acknowledgement Settings.

Also don't copy Resources/Licenses directory contents to bundle resources,
we don't need this extra data at run-time. License info is already in the
Settings.bundle.
