Do not assert Apache license on generated projects

If I do `cordova create` to generate a project the generated `www` code includes Apache copyright/license statement. I would rather see the template code under CC0 or public domain license, or a statement that Apache Cordova does NOT assert copyright and license on the generated code. (If I generate a project with Xcode, it seems to mark the code with copyright to my own name.)

Start by tracing the templates used by `cordova create` and inspecting the generated `www` code. The work is done when generated projects no longer assert Apache copyright or licensing on that code, using the project's chosen CC0, public-domain, or explicit non-assertion wording.
