Removed jurisdiction param & add warning text

By removing the jurisdiction url param we get the CC 4.0 licenses
instead of the CC 3.0 licenses. Also started with adding a function to
deal with adding a warning text about the scope of a license
Merge branch 'develop' of github.com:tarmot/wp-cc-plugin into develop
Renamed files and references to use WPLicense

Either use WPLicense or all lowercase wplicense for this plugin.
